Helpppp!!!! Further Mechanics

A centrifugal clutch with two sliding clutch plates is required to transmit a torque of 20Nm at a speed of 150 revs per min. The coefficient of friction between the clutch drum and clutch plates is 0.28. The radius of the centre of gravity of each sliding clutch plate is 0.21 meters and the radius of the inside drum is 0.25 meters. The desperation between the plate and drum when stationary is 0.1m. The spring stiffness is 2kN/m. Q1.Determine the mass of the clutch plate for it to be effective. Q2. Determine the power required to run this system. Q3.determine the required speed and power to transmit a 20% increase in torque.

(IMO) Without a diagram, it is difficult visualize problem at hand especially for people like me who are unfamiliar with the topic of centrifugal clutch.

You may want to post what are your thought on approach the problem and what are you stucked at. I believe your lecture note should have some worked examples that you can learn from them to solve such problem.

What do you mean by "The desperation between the plate and drum when stationary is 0.1m."?

I have not heard about the usage of the term "desperation" in this way in physics.

Do you have the answers?
