Solve the below problem:
Q: Blocks A and C are connected by a rope that passes over drum B. Knowing that the drum rotates slowly clockwise and that the coefficients of friction at all surfaces are µs =0.30 and µk = 0.20, determine the smallest mass of block C for which block A
(a) Will remain at rest,
(b) Will be in impending motion up the incline,
(c) Will move up the incline at a constant speed.
