The rigid bar ABCD is suspended from four identical wires. Determine the tension in each wire caused by the load P shown.
(a) Draw a free body diagram of rigid bar ABCD.
(b) Using static equilibrium, write down force and moment equilibrium equations.
(c) Use the deflection of the rigid bar ABCD to determine the relationship between deflections between points A, B, C, and D.
(d) Use the equations obtained in steps (b) and (c) to determine the forces in all cables.
