The figure shows a homogeneous. rigid block weighing W = 14 kips that is supported by three symmetrically placed rods. The lower ends of the rods were at the same level before the block was attached. Determine the stress (psi) in the steel rod after the block is attached and the temperature of all bars increases by 106 °F. Use the following data: Rod Area (in2) E (psi) α (/°F) Length (ft.) Each steel rod 0.98 29 x 106 6.7 x 10-6 3 Bronze rod 1.79 12.6 x 106 10.9 x 10-6 9
