(d) Gearbox
Ans: (d) Gearbox
C. Short answer questions
1. Discuss the role of a transmission system.
Ans: The transmission system transfers power from the engine to thewheels, allowing the vehicle to move. It controls the speed and torque bychanging gear ratios and enables smooth engagement and disengagement ofpower through the clutch.
2. Explain the function of a gearbox.
Ans: The gearbox provides different gear ratios to control the speed andtorque of the vehicle, allowing it to move efficiently under varying road andload conditions. It also helps the engine operate within an optimal speed range.
