Question

3. Cast-Iron Weight Using two ropes and a roller chute, two workers unloading a 200 kg cast-iron counterweight from a truck. Knowing that at the instant shown the counterweight is kept from moving and that the positions of points A, B, and C are, respectively, A (0, -0.5 m, 1 m), B (-0.6 m, 0.8 m, 0), and C (0.7 m, 0.9 m, 0), and assuming that no friction exists between the counterweight and the chute, determine the tension in each rope. (Hint: Since there is no friction, the force exerted by the chute on the counterweight must be perpendicular to the chute.) are 2 n
