Question: A disk having an outer diameter a fits loosely over a fixed shaft having a diameter b, if the coefficient of static friction between the

A disk having an outer diameter a fits loosely over a fixed shaft having a diameter b, if the coefficient of static friction between the disk and the shaft is μs, determine the smallest vertical force P, acting on the rim, which must be applied to the disk to cause it to slip over the shaft. The disk weighs W. Given: a = 8 in b = 3 in μs = 0.15 W = 10 lb

wY P.
