Which type of clutch is characterized by centrifugal action for engagement?

• A. Disc clutch
• B. Jaw clutch
• C. Centrifugal clutch
• D. Friction clutch

Answer: (C)

The centrifugal clutch is specifically designed to engage based on centrifugal force. As the engine speed increases, the clutch shoes or weights move outward due to the centrifugal force generated, which then engages the clutch. This mechanism allows for automatic engagement when a specific speed threshold is reached, making it particularly useful in applications where manual control is not practical, such as in scooters or lawn equipment.

In contrast, a disc clutch typically relies on pressure applied to the disc surfaces to engage and disengage, irrespective of engine speed. A jaw clutch engages through a mechanical interlocking of male and female parts but does not rely on centrifugal force. Meanwhile, a friction clutch uses friction material to create engagement, which also does not involve centrifugal action. The distinct operating principle of the centrifugal clutch sets it apart, emphasizing its unique design and functionality in specific applications.
