A plate clutch consists of 1 pair of contacting surfaces. The inner and outer diameter of the friction disk is 100mm and 200mm respectively. The coefficient of friction is 0.2 and permissible intensity of pressure is 1.5N/mm². Assuming uniform wear theory, calculate the torque transmitting capacity of the clutch.

(a) 412.23N-m

(b) 353.43N-m

(c) 334.53N-m

(d) 398.34N-m

I received this question by my instructor.

This theoretical question is from the Friction Clutches unit in lesson Friction Clutches, Brakes, Belt Drives and Chain Drives of Machine Design
