20.2.4
To the cylinder, which rotates under the action of a pair of forces with a moment M = 20 N • m, the brake shoe is pressed with the force F = 100 N. Determine the generalized force corresponding to the generalized coordinate? If the sliding friction coefficient between the shoe and the cylinder is f = 0.4, and R = 0.4 m (Answer 4)
