In a repair shop a truck engine that has mass 425 kg is held in place by four light cables (Figure 1). Cable A is horizontal, cables B and D are vertical, and cable C makes an angle of 37.1 with a vertical wall. Tension in cable A is 721 N. What is the tension in cable b? What is the tension in cable c?

In the figure, the weight w is 56.4 N.  a. What is the tension in the diagonal string? b. Find the magnitudes of the horizontal forces F1 and F2 that must be applied to hold the system in the position shown.

Jason is pulling a box across the room. He is pulling with a force of 24 newtons and his arm is making a 69 angle with the horizontal, what is the horizontal component of the force he is pulling with?

A construction worker pulls on a crate of mass, m, on level ground via a light, uniform cable that is attached to the crate at an angle, 0, above the horizontal. As a result of the force applied by the worker, the cable acquires a tension, T. What is the normal force of the ground on the crate? Neglect friction between the crate and the surface. (See the diagram below.) T Crate a. mg - Tsine b. mg + Tsine C. mg + Tcose d. mg O e. mg - Tcose

A crate hangs from a rope that is attached to a metal ring. The metal ring is suspended by a second rope that is attached overhead at two points, as shown. What is the angle 0 if the tension in rope 1 is 1.63 times the tension in rope 2? Rope 2 = Rope 1

The pair of pulleys is used to lift a 40-kg block 0.25 m. The constant upward acceleration of the block during the lift is +2.5 m/s^2, and the pulleys and rope have negligible inertia and negligible friction. A. What is the tension in the pulling rope? Express your answer with the appropriate units. B. What is the tension in the rope from which the block hangs? Express your answer with the appropriate units. C. Determine the magnitude of the force exerted by the upper mount on the top pulley. Express your answer with the appropriate units. D. How much work is done by the person pulling the rope in lifting the block 0.25 mm? Express your answer with the appropriate units. E. By how much does the kinetic energy of the block change in this process? Express your answer with the appropriate units. F. How much work is done on the block by the rope attached to it? Express your answer with the appropriate units. G. How much work does the ceiling do in this process? Express your answer with the…
