The system of two blocks, cable, and fixed pulley is
initially at rest. Determine the horizontal force P
necessary to cause motion when (a) P is applied to
the 5-kg block and (b) P is applied to the 10-kg block.
Determine the corresponding tension T in the cable
for each case.
Ans. (a) P = 137.3 N, T = 112.8 N
(b) P = 137.3 N, T = 24.5 N
