Its all logical question on the basis of automobile engine and vehicle including aptitude questions.

Q1. Where the most torque in the vehicle induced? At the output shaft or wheel?
Ans. 
Torque is induced at the output shaft of the vehicle.
• Torque is typically induced at the output shaft of the vehicle, where the engine power is transferred to the transmission system.

• The output shaft is responsible for transmitting power to the wheels, where the torque is then used to propel the vehicle forward.

• In some cases, additional torque can be induced at the wheels themselves, such as in electric vehicles with in
