Question
A load P is supported by a structure consisting of rigid bar ABC, two identical solid aluminum alloy [E = 73 GPa] rods (1), and a solid
bronze [E = 105 GPa] rod (2). The aluminum rods (1) each have a diameter of 17 mm and a length of L1 = 2.7 m. They are symmetrically
positioned relative to middle rod (2) and the applied load P. Bronze rod (2) has a diameter of 25 mm and a length of L2 = 1.5 m. If all
bars are unstressed before the load P is applied, determine the normal stresses in the aluminum and bronze rods after a load of P = 60
kN is applied to the rigid bar.
