D) It improves the alignment of the clutch plates

C) It cools down the clutch plates

6 / 12

Question 5:
What is the effect of a loss of air pressure in an air-operated radial tyre type clutch?

D) The engine speed will increase

C) The clutch will automatically disengage

A) The clutch may become stuck in the engaged position

B) The engine will automatically shut down

7 / 12

Question 1:
With reference to pneumatic clutches used for medium-speed main propulsion purposes, what is the primary function of the pneumatic system in the clutch operation?

D) To adjust the speed of the engine directly

A) To provide lubrication to the clutch plates

C) To cool the clutch plates and prevent overheating

8 / 12

Question 2:
In a pneumatic clutch system, what component is primarily responsible for applying the clamping force to the clutch plates?

A) Air compressor

B) Pneumatic actuator

D) Flywheel

C) Torque converter

9 / 12

Question:
With reference to pneumatically operated friction clutches, what is the effect of angular misalignment?

C) Enhanced torque transmission and longer clutch life

A) Improved engagement and smoother operation
