A plate clutch experiences an axial force of 4000 N. The inside radius of contact is 50 mm, and the outside radius is 100 mm. 4.1 Determine the maximum, minimum, and average pressure when uniform wear is assumed. A multidisc clutch has 4 steel disks and 3 bronze disks, and each surface has a contact area of 2.5 x 103 m and a mean radius of 50 mm. The coefficient of friction is 0.25. 4.2 What is the power capacity for an axial force of 350 N if the clutch rotates at 400 rpm. Assume uniform wear in the clutch plates?
