Question:
A 10-lb block B rests as shown on a 20-lb bracket A. The coefficients of friction are (s 0.30 s and 0.25 (k = 0.25 between block B and bracket A, and there is no friction in the pulley or between the bracket and the horizontal surface.
(a) Determine the maximum weight of block C if block B is not to slide on bracket A.
(b) If the weight of block C is 10% larger than the answer found in a determine the accelerations of A, B and C.
