When a clutch is fully engaged, what occurs?

When a clutch is fully engaged, what occurs?

• A. The input shaft stops rotating due to friction
• B. The release bearing pushes the pressure plate away
• C. A force is placed against the shifter sleeve through a bearing. The shifter squeezes a set of friction discs together
• D. The flywheel unhooks from the crankshaft

Answer: (C)

Clutch engagement means the pressure plate applies force to clamp the clutch disc against the flywheel, so the engine’s crankshaft and the transmission input shaft rotate together and torque is transferred to the transmission. The release bearing’s job is the opposite—it moves the pressure plate away to disengage the clutch. The flywheel doesn’t detach from the crankshaft, and the input shaft doesn’t stop rotating when the clutch is engaged. The idea behind the correct choice is the act of pressing the friction discs together so power can flow from engine to transmission; the terminology in some descriptions may call the actuator a “shifter,” but the essential action is the clamping of the discs to connect the two rotating parts.
