Clutch Calculation

A single plate clutch (2 friction surfaces) can operate at a maximum lining pressure of 1 MN/m2. The inner diameter is 140 mm, the outer diameter is 200 mm and the coefficient of friction is 0.5. If the clutch is operating in the uniform wear mode, what is the maximum torque that can be transmitted and the required normal force.
