The copper bar has a length of 2.0 m, a cross-sectional area of 4800 mm 2 , and a modulus of elasticity E c 5 120 GPa. Each steel post has a height of 0.5 m, a cross-sectional area of 4500 mm 2 , and a modulus of elasticity E s 5 200 GPa. (a) Determine the downward displacement d of the lower end of the copper bar due to a load P 5 180 kN. (b) What is the maximum permissible load P max if the displacement d is limited to 1.0 mm?
