Question
![A 150-lb block is placed on a 33° incline and released from rest. The coefficient of static friction between the block and the incline μs
is 0.46. (a) Determine the maximum and minimum values of the initial tension T in the spring for which the block will not slip when
released. (b) Calculate the friction force F (positive if up the slope, negative if down) on the block if T = 108 lb.
Assume W = 150 lb, 0 = 33º.
Answers:
