Example Problem #5: The motor and platform weigh 3500 lbs and are being suspended in equilibrium using three cables (attached at B, C, and D). A vertical lifting force is applied at the ring at A. Disregard the weights of the cables and spring. It is desired to determine the magnitudes of the forces in each of the three cables. (a) Draw the FBD of the ring at A. Write the vector equilibrium equation(s) for the Free Body under consideration. (b) (c) Write all forces using vectors. (d) Determine the magnitude of the tension in each of the cables needed to maintain equilibrium. 2. Answers 3000 lbs los AC 1460 20 ft 4 ft 8 ft 6 ft 6 ft 4 ft 8 ft
