Question: A solid brass cylinder with a cross-sectional area of 3226 mm2 is placed inside a steel tube having a cross-sectional area of 5162 mm2. Both the cylinder and the tube are 216 mm long. They stand on end on a flat rigid surface and they support a rigid block. A load of 580 kN is applied to the block. Calculate the stress in each material. 11.57 Three 1 4 -in.-diameter wires are symmetrically spaced and are 20 ft long, as shown. The outer wires are steel and the middle wire is bronze. The wires support a rigid horizontal steel box weighing 2000 lb. Calculate
a. the stresses in the wires.
b. the total elongation of the wires.
