Question:
The brake is to be designed to be self locking, that is, it will not rotate when no load P is applied to it when the disk is subjected to a clockwise couple moment MO. Determine the distance d of the lever that will allow this to happen. The coefficient of static friction at B is μs.
Given:
a = 1.5 ft
b = 1 ft
μ s = 0.5
