Driving theory test study materials

Driving Standards Agency (DSA) has introduced the Driving Theory Test on 1st July 1996 in UK. In order to improve the road safety skills DSA has made compulsory theory test which must be passed before learners can take the practical test itself.

Before driving any vehicle (car, motorbike etc), learners should check that they meet all of the legal requirements in United Kingdom. According to Driving Standards Agency (DSA) drivers has to pass theory test first before applying for driving license.

There are many resources where driver can learn driving theory test and practical test. Learner can learn to drive with the proper driving instructor and can drive safely on the road.

Driving theory test consists of two sections, a multiple choice exam and a hazard perception test.

A. Multiple choice elements in driving test:

The theory test is a computer-based test at various tests centers around the country. This section is designed to test your understanding of the theory behind driving. You have 57 minutes to complete the test. There is a 15-minute practice session you can work through before starting the tests. The questions in each multiple choice test vary according to the category of vehicle you’re hoping to obtain a license for, i.e. a motorcycle theory test will contain specific questions that don’t appear in any other test.

For cars and motorcycles you’ll be asked randomly selected 50 multiple-choice questions in 57 minutes and you need to get at least 43 right to pass.

B. Hazard perception test:

Hazard perception test is a second part of the driving theory test and must be passed at the same time. The main aim for this test is to tests your alertness of potential hazards while driving. This part is also delivered on a computer but learner has to react by clicking a mouse button.

This test includes a series of 14 hazard video clips each about a minute long, which have every day road scenes. Each clip contains at least one developing hazard, but one of the clips will feature two developing hazards. The videos feature various types of hazard, such as vehicles, pedestrians and road conditions.

There are many other resources where learner can learn and drive theory test. Such as:

Theory test book: Driving Theory test book include latest entire 2012 driving theory test revision questions with answers. This book is a important study material to prepare and pass your theory test

The Highway Code book: The Highway Code is imperative reading for everyone. This is very beneficial to know road traffic signs, rule and regulations if you are preparing for your driving theory test or practical test.

It is important that all road users are aware of the Code and are considerate towards each other. This applies to pedestrians as much as to drivers and riders.

Hazard perception clips: Hazard perception test has been brought in the driving theory test because new drivers are indirectly involved in accidents. It has been approved that drivers who have taken hazard perception test training have much better hazard test skills. Many learner drivers go wrong in hazard perception test, mainly because of lack of knowledge about the hazard test itself. If you understand the hazard perception test, how it works, how to score, what to look for etc, it’s not at all difficult to score good in the hazard test.

Driving test CD: Preparing for your driving test exam by getting at recent theory test questions. It helps to learn theory question and practice where you are weak in hazard perception test.

Driving theory test software: Driving theory test software can be access completely online official car, motorbike DSA driving theory test questions bank. It helps to learn theory, practice where you are weak, monitor your progress, help to get ready for exam, hazard perception test etc.

Prepare with these all study materials and pass your test with confidence.

Sketching the Working Theory of Jaw Crusher

Jaw crushers for crushing rock and other minerals conventionally comprise a fixed jaw and a movable jaw which define a crushing chamber of a cross section which narrows from top to bottom. The movable jaw is pivotally supported at its upper end so that the lower end of the jaw can be driven in a swinging motion towards and away from the lower end of the fixed jaw. Material to be crushed is introduced into the upper end of the crushing chamber formed between the two jaws and is crushed between the two jaws by the swinging movement of the movable jaw as the material moves downwardly through the chamber, the crushed material being discharged from the chamber at its lower end. The crushing surfaces of the two jaws are subject to substantial wear and are conventionally formed by replaceable faces which are fixed to the body of the jaw by being bolted and keyed. Usually, to facilitate breakage of the rock the surface of each replaceable jaw face is corrugated, with the axes of the corrugations extending in a vertical direction and normally each jaw carries two separate jaw faces, namely an upper face and lower face.

The primary effect of the corrugations is achieved at the lower, narrow, end of the crushing chamber, and in order to generate the necessary breaking forces the opposed jaw faces of the two jaws are so arranged that the peaks of the corrugations of one of the jaw faces align with the troughs of the corrugations of the other jaw face. As a result of this, with conventional jaw faces there is limited scope for interchangeability of the various jaw faces to compensate for wear, most of which occurs at the lower end of the crushing chamber; for example with conventional jaw faces the upper and lower jaw faces or each jaw could be interchanged but there is not complete flexibility to interchange the four jaw faces while retaining the required relationship between the sets of corrugations.

Jaw crushers have many advantages, such as big reduction ratio, equal product granularity, simple structure, reliable working condition, convenient repair and economical operation, which are widely used for mine, smelting, building material, road, railway, irrigation works, chemical and materials with cold compression strength no more than 320 MPa.

Why hazard perception test was introduced?

New drivers are disproportionately involved in road accidents, especially in the first months after passing a Driving test exam. It has been proven that drivers who have taken Hazard perception test training have much better hazard perception skills.

About hazard perception test –

The hazard perception test tips are online computer-based tips, which measure driver’s ability to anticipate and appropriately respond to potentially dangerous situations while driving.

In hazard perception test, you will see video clips of genuine, traffic scenes filmed from the driver’s perspective. When you watch the clips, you need to imagine that you are the driver.

In each hazard clip there will be at least one developing hazard, but one of these clips will feature two developing hazards. As early as you can, you will need to watch the clip carefully and try to predict the traffic hazard. you need to respond straight away, as soon as you predict that a traffic hazard is likely to happen. A traffic hazard is something that would require the driver to take some action like overtake, slow down or change course.

Rather the potential hazards, the hazard perception test are designed to get the candidate to identify ‘Developing Hazards’.

For example: School sign is not a developing hazard, but if you see school children about to cross the road, then it becomes a developing hazard and needs to be identified.

Watch out for following hazards, as these are the likely situations where developing hazard may turn in to actual hazard, while appearing for the hazard perception test

Vehicles make the road narrow
Junctions and roundabouts
Horse riders
Loose pets and farmyard animals
Vehicles emerging from side roads, parking places or driveways
Large vehicles moving over to your side of the road
Changes in the traffic movement and volume
Weather conditions of the day
Pedestrians or cyclists crossing the road
Meeting oncoming vehicles on narrow roads or where other obstructions or slow moving

Hazard perception test scoring mechanism:

Each scoring window is divided into five equal sections and a score of five through to one allocated to each. Those responding in the first section of the scoring window will score 5 and those in last segment a score of 1. Responses outside the window will score zero.

Scoring in hazard perception test is not difficult at all. You need to practice variety of clips and understand the DSA theory test.

New changes in DSA driving theory test

We wish you all a safe and happy new year!

Learning to drive car/motorbike?
Are you planning to give your DSA motorbike theory test / car theory test anytime soon?

You should be aware of the new changes in DSA theory test.
From 23 January 2012 the theory test will be made up of multiple-choice questions which are no longer published in learning materials.

The reason behind the move is to stop candidates from simply memorizing theory test questions and answers and learning by rote.

If you are taking your theory test before 23rd Jan 2012, you will be asked the exact same questions as they are published here. But if you are taking theory test after 1st January 2012, you need to know about the changes in the UK theory test.

The questions in the exam will not be exactly same as they are published.
The DSA will not distribute the real/exam questions.
Real/live exam questions will not appear in any product – book, CD, driving test dvd, mobile applications or on any website.
So your test would contain questions which are unpublished.

The official DSA explanations for every revision question will help candidates fully understand the answer. This approach to learning will help candidates to gain a better knowledge and understanding of driving theory which will help them respond correctly to the new, reworded live questions used in the actual test.

No changes are being made to the format of the theory test. It will still be made up of a multiple-choice part and a hazard perception part. The time allowed and the pass marks will stay the same.

You can download car/bike DSA theory test application containing all latest 2012 questions with answers. You can also solve interactive hazard perception clips.

We would like to assure you that the tests will not be any difficult.
But once you pass the test, your understanding of the theory would be better which will help you while driving on the road.

We wish you good luck in your DSA theory test.

How Einstein Received the Theory of Relativity

Einstein was one of the most creative geniuses of the past century. He said, “I want to know God’s thoughts, the rest are details.” And know God’s thoughts he did. The theory of relativity, E = MC2, gave birth to quantum physics and altered forever how scientists look at energy and matter and time and space.

What was Einstein’s secret?

How did Einstein get this brilliant creative insight into the realm of physics? He tells that he was lying on his back in a grassy field, looking through half-closed eyes and wondering what it would be like to ride on a ray of sunlight. Intuitively, the theory of relativity came to him. He went back to his office and proved it with mathematical formulas.

Now consider the priciples we find in Habakkuk 2:1-2 and Revelation 1:9-10 for how the prophets Habakkuk and John connected with divine flow. They quieted themselves down, looked for vision, heard God’s voice, and wrote it down.

“I will stand at my watch and station myself on the ramparts; I will look to see what he will say to me, and what answer I am to give to this complaint. The LORD’s Answer… Then the LORD replied:‘Write down the revelation and make it plain on tablets so that a herald may run with it.’” – Habakkuk 2:1-2

How many of the four principles was Einstein following to help him connect with divine flow?

1) He was still (quieted down);
2) He was using vision (imagination & divine vision);
3) He was tuned to spontaneity (God’s voice);
4) He wrote it down (journaling).

So we see that Einstein used all four. I have discovered that people who will use all four of these principles in collective combination find that they are able to capture and release the divine flow of God within them on a continuous, ongoing basis. So, you see, Einstein was a modern day example of a man using the four keys which Habakkuk and John used to release divine creativity in the field of science.

You can connnect to the divine flow, too.

When you know what to do to connect to the divine flow of God, and you do these things, then your life is a channel of divine creativity. Your life begins to match the covenant promises of Deuteronomy 28:1-14, and begins to reflect the glory of Solomon’s kingdom, which was an outworking and fulfillment of these principles. It will cause non-believers, like the Queen of Sheba, to come and see the expressions of divine creativity which flow from your life. They, too, will be breathless, declaring that only God could do this (11 Chron. 9:1-8).

May you be a vessel through which divine creativity flows. May the world see the unfolding drama of God’s creativity displayed in their midst by the artists in the Church. May God be glorified in our midst.

The Contemporary Office Design Theory

The overall design of an office space greatly affects the mood and productivity of all those working in it. This is called office psychology where every element affects the general attitude of people inside an office space in Reston VA. The design and style are often a matter of personal perspective. However, people can never go wrong with sophisticated contemporary designs. The kind of business does not matter as long as the walls and element placement follows modern office design.


Today, the traditional style of offices which required individual spaces is no longer ideal. Contemporary office design theories argue for a concept of collaboration which aims to break the walls that limited and separated employees. The modern design of today’s offices focuses on sets of stations, allowing employees to interact with each other. This line of thought builds upon the concept of socialization to augment an employee’s critical thinking and productivity through intellectual discussions.


Moreover, the reception of contemporary office designs is characterized by bright, open and warm welcoming areas. The standard design of the reception area provides space for the company to display awards, on-going projects, and other important details. Modern offices also display abstract artworks or historical elements valuable to the company.


The company’s lobby is also one of the most critical areas in modern office design. Contemporary design boasts comfortable and spacious seating, substantial reading materials, and even refreshments.  A modern lobby displays sleek and sophisticated furnishings, and neat surfaces.


One of the most distinct characteristics of contemporary office design is the clusters of desks and storage called systems furniture. This feature saves companies construction costs while allowing efficiency in restructuring. Such a system also makes for flexibility with different sizes and shapes, allowing employees to talk over low partition walls.


Desks and storage systems hang from the walls providing employees easy access to files and supplies. While everyone are relatively more “open” compared to traditional design, contemporary office still provides the needed privacy for each employee. System furniture is not unique to contemporary design as it has existed for many years. Modern designs were adopted as technology advanced and made lighter colors and thinner walls available for company use. New materials such as plexiglass were also used to allow a more open feel in an office space in Ballston VA.


Lastly, the lighting of contemporary offices supports the green revolution. New office spaces are embedded with light sensors to monitor room activity.  If the sensors detect no activity, the lights in the specific area turn off, and vice versa when a person passes through the lights. For instance, an office space in Arlington VA employs modern energy efficient lighting techniques. Such offices utilize environment friendly bulbs like LEDs or Xenon for clear lights.

Testing Theory of Insulation Resistance Tester

Insulation resistance tester is extensively utilized to test engine, motor, electric adapter, attached wires, digital items and also of electric equipment such as cables for control, signal, telecommunication and electricity. Insulation resistance tester is applied to illustrate the change of insulated resistant of electric machines for months and yrs. The insulated resistance can be with giant changes. That would illustrate the possible troubles. Therefore, we might require to rectify the insulation resistance tester from time to time with the ambition to make sure no change of the tester throughout the long-term utility.


Nearly all kinds of insulation resistance tester would applycccm of protecting the ends is to remove the possible stream leakage and optionally reduce the influence to the output resistant gadget to 0.

One of main difficulties to rectify the insulation resistance tester is to find the proper resistance. The 1st requirement should certainly be on adequate precision. And, the resistance level should be big enough to endure the high level of DC stream. Besides, there exists no universal standard for Megger machine manufacturers to apply specific sorts of resistant range. So, users may need to have all kinds of resistance levels. By understanding different kinds of insulation resistance tester goods, users can know different feature testing points of them.


Multifunctional electrical/electronic calibrator cannot be utilized to correct the insulation resistance tester due to the limited voltage they can only deal with. The best voltage is not over 20V. Also, the strategy for composite voltage would be excluded based on the restrain of design cost and size. The rectification of insulation resistance tester applies vertical high-voltage resistant matrix to provide over 500 thousand output resistant levels. In the rectifier of insulation resistance tester, there are 8 ranges of resistances. Each range can provide 4.5-digit stable output. It would be another challenge to collect proper high-voltage resistances and then integrate them into a device. The protector of insulation resistance tester can form a resistance multiplier to efficiently multiplie a known resistance.

Satellite TV receiver systems theory


Digital Satellite TV has developed rapidly in recent years, the use of geostationary satellites to digital encoding of television signal transmission to the client as a form of radio and television. There are two main ways. One is the digital TV signal transmission to the cable end, and then converted to analog by a cable television station sent to the user’s home. This form has been popular in the world for many years. Another way is to transmit digital TV signals directly to the user’s home that is: Direct to Home (DTH) mode. U.S. Direct TV is the first application of this technology

Satellite TV Preview

Satellite television operating companies. Compared with the first approach, DTH satellite emission power mode, the antenna can be smaller, the average family can use. At the same time, can provide user authentication and encryption management to digital television, pay per view television (PPV), high-definition television and other types of advanced television services, without the middle part of restrictions. In addition, methods can also carry out a number of DTH television services other than digital information services, such as the INTERNET high speed downloads, interactive television.
DTH in the international arena there are two standards, the European standard DVB-S and U.S. standards DigiCipher. But increasingly in the global DVB standard widely used in the emerging U.S. DTH company Dish Network also uses the DVB standard.


A typical DTH system consists of six parts:

1) front-end system (dreambox 500)

Front-end system consists of video and audio compression encoders, multiplexers and other components. The main task is to front-end system for digital television signal encoding, the use of statistical multiplexing technology, in a limited frequency band satellite transponders to transmit more programs. DTH by MPEG-2 standard for video and audio signal compression, using dynamic statistical multiplexing technology, can upload a 27MHz transponder vote Chi? 0 sets of TV shows.

2) transmission and uplink system (Uplink)

Transmission and uplink systems, including front-to-uplink station communications equipment and uplink equipment. Transmission main IF transmission and digital baseband transmission two.

Receiver (18)

3) Satellite (Satellite)

DTH systems use high-power direct broadcast satellite or communications satellite. Due to technical and cost reasons, some DTH system uses high-power communications satellite, the United States and Canada adopt a more appropriate DTH company dedicated high-power direct broadcast satellite (DBS).

4) User Management System (SMS)

DTH user management system is the heart of the system, mainly the following functions: Xiaobian recommend

A. Registration and management of user information.
B. purchasing and packaging programs.
C. Development of program standards and user billing charges.
D. Market forecasts and marketing.

User management system mainly consists of user information and program information database management system and to answer user questions and provide a variety of customer service Call Center form.

5) The conditional access system (CA)

Conditional access system has two main functions:

A. The program data encryption.
B. of the program and authorize users.

DTH on the current international system of conditional access systems used are: U.S. NDS, Israel, Irdeto, France Via Access, Switzerland, Nagra Vision, etc.

U.S. companies and the use of Direct TV Direct TV Star Choice Canadian technology companies using NDS conditional access system; U.S. Dish Network (Echostar) and the use of Echostar’s technology companies in Canada to use Bell ExpressVu is the Nagra Vission conditional access system.

6) users receiving system (IRD)

DTH users receiving system consists of a small satellite dish antenna (Dish) and integrated receiver decoder (IRD) and smart card (Smart Card) form.
IRD is responsible for four main functions:

A. decoded program data stream, and output to a TV.
B. The use of smart card key (Key) to decrypt.
C. receive and process a variety of user commands.
D. Download and run the variety of applications.

DTH system, the IRD is not a simple hardware device, it also includes a large number of operating systems and application software. IRD is currently more successful operating system is Open TV. U.S. Dish Network has begun to gradually upgrade the user’s IRD to Open TV system.

Front-end system consists of video and audio compression encoders, multiplexers and other components. The main task is to front-end system for digital television signal encoding, the use of statistical multiplexing technology, in a limited frequency band satellite transponders to transmit more programs. DTH by MPEG-2 standard for video and audio signal compression, using dynamic statistical multiplexing technology, can upload a 27MHz transponder vote Chi? 0 sets of TV shows.

Term Paper: Herzberg’s Two Factor Theory

Herzberg classified the human needs into two factors which are

Hygiene or extrinsic factor
Motivators or intrinsic factors

The hygiene factors primarily comprise of the administration, supervision, working conditions, and salary, and if these needs are not satisfied the employee may become dissatisfied with the job. Similarly the second kind is that of the motivators that include recognition of their job, responsibility and growth. These needs are fulfilled by an individual’s work and performance at the job (Dawson, 1987).

After we have analyzed the most important theories of motivation it could be said that there is no fixed pattern from which a person can become motivated. It is often observed that professionals that are on the upper management of an organization are not much motivated by the extrinsic factors reason being they have made enough money, they have all the luxuries in the life and their basic needs are fulfilled so money is not a motivational factor for them. What motivates them is a challenging job, or a new venture, or some creative job where they can demonstrate their skills. This might not be the case for a mid level manager when his physiological and safety needs are fulfilled but the quality of life that he has in his mind is not yet achieved. This means that until that need is not fulfilled he would not move up to the other need (Kulkaa, 2005).

A survey was conducted in order to know that what motivated the employee most and the overall perception that was acquired was that it was cold hard cash that makes people come to work every morning.  Lots of surveys and studies have been conducted lately to investigate the factor which is most crucial for employee motivation and not surprisingly the finding of the survey showed that still there are majority of people who prefer money as motivational factor over other non monetary benefits. The reason why there is a high tendency of money as motivator is because of the high inflation and other economic situations where people are not much sure about their current job and want to make more and more money so as to secure their future. But still a proper balance should be maintained between the monetary benefits and non monetary benefits for the reason that you cannot motivate everyone with the same yardstick.
