Knowing that the mass of the crate is kg, determine the tension in the cable for each of the arrangements shown. Determine the magnitude and direction of the force P that must be exerted on the free end of the rope to maintain equilibrium.
Hint: The tension in the rope is the same on each side of a simple pulley. This can be proved by the methods of Ch. Determine for each arrangement the tension in the rope.
See the hint for Problem 2. The pulley is held in the position shown by a second cable CAD, which passes over the pulley A and supports a load P.
