Chapter 6, Problem 6/88(choose chapter or problem)
An end of the thin board is being sanded by the disk sander under application of the force P. If the effective coefficient of kinetic friction is \(\mu\) and if the pressure is essentially constant over the board end, determine the moment M which must be applied by the motor in order to rotate the disk at a constant angular speed. The board end is centered along the radius of the disk.
