3.3. A steel bar with the dimensions and cross section shown is suspended vertically. Three concentric downward loads are applied to the bar: 22250 N at the lower end, 13500 N at 0.35 m above the lower end, and 9000 N at 1 m above the lower end. The modulus of elasticity of the steel is 210 GPa. What is the total change in length of the bar? 1 m 9000 N 0.65 m A = 6.5 cm? 0.35 m 13500 N (cross section) 22250 N
