Question: The simple band brake is constructed so that the ends of the friction strap are connected to the pin at A and the lever arm

The simple band brake is constructed so that the ends of the friction strap are connected to the pin at A and the lever arm at B. If the wheel is subjected to a torque of M = 80lb ? ft, determine the smallest force P applied to the lever that is required to hold the wheel stationary. The coefficient of static friction between the strap and wheel is ?_s = 0.5.

M = 80 Ib f 20 45 1.25 ft Fisat 1.5 ft -3 ft-
