What connects to the lower control arm? Control arms, sometimes called “A arms,” are the core of your front suspension system. The upper control arm connects to the uppermost area of the front wheel and the lower control arm connects to the lower most area of the front wheel, with both arms then attaching to […]
What is the function of tire?
What is the function of tire? Tires are designed to support the weight of the vehicle, absorb road shocks, transmit traction, torque and braking forces to the road surface and maintain and change the direction of travel. To fulfill these four basic functions tires are made of resilient rubber and filled with compressed air. What […]
What is meant by reliability of a test?
What is meant by reliability of a test? The reliability of test scores is the extent to which they are consistent across different occasions of testing, different editions of the test, or different raters scoring the test taker’s responses. How do you define reliability requirements? There are four basic ways in which a reliability requirement […]

How can we increase the efficiency of a diesel engine?
How can we increase the efficiency of a diesel engine? Run the engine fuel-lean, that is, use excess air. It is well known that fuel-lean running improves the efficiency. Higher compression ratio. We need new cycles put into practical use. Run the engine at optimum conditions, meaning low friction (modest engine speed) and low pumping […]
Why is bitumen used in road construction?
Why is bitumen used in road construction? Asphalt road surfaces are also considered a sustainable option for road paving material where bitumen is used as binder as this material can be recycled. The bitumen, produced by the refineries, plays an important role in road durability which is also important for sustainability. What is the purpose […]
What happens to the potential energy of a ball that is dropped from a height?
What happens to the potential energy of a ball that is dropped from a height? When a tennis ball is dropped from 2 m, it possesses a certain amount of gravitational potential energy because of its mass and its height above the ground. As the ball falls, that energy is converted to kinetic energy. How […]
