A differential is a system that is made to transmit engine’s torque to the wheels. It takes the power which the engine creates and distributes it allowing the wheels to move at different speeds. There are three types of different differentials : Open Differential, Limited-Slip Differential and Torque-Vectoring Differential. The most basic one is the Open Differential, it is made from two shafts. On the ends of both shafts there are gears which create the power distribution the inner shaft has a large gear and the outer shaft’s gear is small. The open Differential mostly benefits of it’s basic design and it is really cheap to produce. However it also has some disadvantages the main one is that these types of differentials split the torque evenly between both wheels and the amount of power becomes limited by the wheel which has the lowest amount of grip. The other two differential types are more flexible and they can transmit different amounts of power through each wheel.

TASK 2. Reading. ANSWER THE TWO QUESTIONS. You need to write at least 200 words for the two answers taken together.
