Q.1) Block A is connected to block B by a pulley
system as shown. The weights of blocks A and B
are 100 lbs and 70 lbs, respectively. Assume
negligible friction between the rope and all pulleys
as well as between block B and the incline and
neglect the mass of all pulleys and cables.
Determine the angle 0 required to keep the system
in equilibrium. (At least two FBDs must be drawn
