Question: * 8 - 9 2 . The simple band brake is constructed so that the ends of the friction strap are connected to the pin

*8-92.
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, and the minimum force P=20lb is needed to apply to the lever to hold the wheel stationary, determine the coefficient of static friction between the wheel and the band.
Ans: s=0.328
