What type of clutch features multiple plates for increased torque capacity?

• A. Single plate clutch
• B. Multi-plate clutch
• C. Cone clutch
• D. Friction clutch

Answer: (B)

A multi-plate clutch is specifically designed with multiple friction plates to increase the torque capacity compared to a single plate clutch. The arrangement of multiple plates allows for a larger surface area which enhances grip and friction, enabling the clutch to handle greater loads without slipping. This design is particularly useful in applications where high torque is required, such as in racing vehicles or heavy machinery.

In contrast, a single plate clutch typically features only one friction disc, limiting its torque transfer capacity. A cone clutch uses a conical shape to engage and disengage but does not increase torque capacity through the use of multiple plates. A friction clutch is a broader term that encompasses various types of clutches, including single and multi-plate variations, and does not specifically refer to one that uses multiple plates. Thus, the multi-plate clutch stands out as the optimal choice for applications requiring enhanced torque capacity.
