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.
