Question:

Blocks A and B are connected by a cable that passes over support C. Friction between the blocks and the inclined surfaces can be neglected. Knowing that motion of block B up the incline is impending when 16 WB = lb, determine

(a) The coefficient of static friction between the rope and the support,

(b) The largest value of WB for which equilibrium is maintained.
