Scaffold Problem



The scaffold of mass m, is being raised by the rope and system of pulleys as shown. The clearance is 1.5L. Determine the tension in the cable at the point the scaffold lifts off the ground. Also determine the angle the scaffold makes with the horizontal at this point. (ans: T = 0.3400 mg, angle = 61.4 degrees).

Also determine the same values when the clearance is 2L.
