Question

13. The system is released from rest in the position shown. The masses of the collar A and the box B are mA = 90 kg and mB = 136 kg. (a) Determine the maximum velocity attained by the collar A as it rises. (b) What maximum height relative to the initial position is reached by the collar A?

13. The system is released from rest in the position shown. The masses of the collar A and the box B are mA = 90 kg and mB = 136 kg. (a) Determine the maximum velocity attained by the collar A as it rises. (b) What maximum height relative to the initial position is reached by the collar A?

Explanation / Answer

b) Max height when accl. and velocity is zero
so 136g = T
Tcos = 90g

=> cos = 90/136

= 48.56 deg

tan = 2/hmax

hamx = 1.765m

a) sorry for this part
