(8%) Problem 11: A man is attempting to lift a crate with a double-pulley system, as shown. A single rope is routed from the ceiling, through the two pulleys, and to where the man pulls on it. The crate has mass m; = 76 kg, and the man has m1 = 75 kg. He pulls downward on the rope with a force of magnitude F = 539 N. The pulleys are both massless and frictionless, and the rope is ideal. tllccxpcrtta.com D A 25 % Part (a) Let T be the tension in the rope. Enter an expression for the sum of the forces in the y direction acting on the crate.
