A load P is supported by a structure consisting of rigid bar ABC, two identical solid bronze [E= 15,000 ksi] rods, and a solid steel [E= 30,000 ksi] rod. The bronze rods (1) each have a diameter of 0.625 in. and they are symmetrically positioned relative to the center rod (2) and the applied load P. Steel rod (2) has a diameter of 0.375 in. If all bars are unstressed before the load P is applied, determine the normal stresses in the bronze and steel rods after a load of P= 14 kips is applied.

A rectangular steel block is 3 inches long in the x direction, 2 inches long in the y direction, and 4 inches long in the z direction. The block is subjected to a triaxial loading of three uniformly distributed forces as floows; 48 kips tension in the x directio, 60 kips compression in the y direction, and 54 kips tension in the z direction. If v = 0.30 and E = 29 x 106 psi, determine the single uniformly distributed load in the x direction that would produce the same deformation in the y direction as the original loading.
