A plank is suspended by 4 steel cables each with a diameter of 0.25 inches and length of 2 meters. Determine to load the system could support before the cables failed. How much would the cable stretch before breaking? Young’s modulus for steel is 20 x 1010 Pa. The ultimate tensile strength for steel is 5 x 108 N/m2
