A long, rectangular copper bar under a tensile load P hangs from a pin that is supported by two steel posts (see figure). The copper bar has a length of 2.0 m, a cross-sectional area of 4800 mm2, and a modulus of elasticity Ec = 120 GPa. Each steel post has a height of 0.5 m, a cross-sectional area of 4500 mm2, and a modulus of elasticity Es = 200 GPa.
(a) Determine the downward displacement δ of the lower end of the copper bar due to a load P = 180 kN.
(b) What is the maximum permissible load Pmax if the displacement δ is limited to 1.0 mm?
