The hoisting cables BA and BC each have a
length of 6 m. If the maximum tension that
can be supported by each cable is 400 kg,
determine the maximum distance AC
between them in order to lift the uniform
550kg truss with constant velocity.
The continuous cable that wraps around the small pulleys at A, B, C, and D has a length of 8m.
The springs are both unstretched when d = 4m. Neglect the weight of the pulleys and cords.
If the mass of each block is 25 kg and it causes each spring to be stretched by 500 mm,
determine 1) the angle 0 when the 2 blocks are applied; (2) the tension on the continuous
cable; and (3) the spring constant k (N/m). Use g= 9.81 m/s².
