Question

two technicians are discussing the dry clutch system on a manual transmission. technician a states that when depressing the clutch pedal, the clutch disc is squeezed harder and the clutch is applied. technician b states that the clutch pedal is depressed (pushed) when changing gears because it interrupts torque transfer from the engine to the transmission. who is correct?

a. technician a

b. technician b

c. both technician a and technician b

d. neither technician a nor technician b

Explanation:

To determine who is correct, we analyze the clutch system operation:

• When the clutch pedal is depressed in a manual transmission, the clutch is disengaged (not applied). Disengaging the clutch interrupts torque transfer from the engine to the transmission, allowing smooth gear changes.
• Technician A is incorrect because depressing the pedal disengages the clutch (does not squeeze the disc harder to apply it).
• Technician B is correct as depressing the pedal interrupts torque transfer for gear changes.

Answer:

b. Technician B
