How is the clutch shown in the attached illustration engaged? Illustration GT-0018
AI Explanation
The correct answer is B) Clutch engages automatically when input shaft flange is rotating faster than the output assembly.
The clutch shown in the illustration GT-0018 is likely a friction-based clutch mechanism. In such systems, the clutch automatically engages when the input shaft (connected to the prime mover) is rotating faster than the output assembly. This allows the transfer of power from the input to the output, engaging the clutch without any manual intervention.
The other answer choices are incorrect because: A) Pneumatic pressure is not the mechanism for engaging this type of clutch; C) The clutch is not engaged manually prior to startup; and D) The clutch does not engage automatically once the output assembly begins rotating, but rather when the input shaft is rotating faster.
