Question

A bronze bar is fastened between a steel bar and an aluminum bar as shown in Figure: Q 3(a). Axial loads are applied at the positions indicated in the figure. Draw free body diagram of each bar and find the value of P if overall deformation of the bar is 5.0 mm. Assume that the bars are rigid enough to prevent buckling. Modulus of elasticity of steel, aluminum and bronze are = 200 GPa, = 70 GPa, and = 83 GPa respectively

a) A bronze bar is fastened between a steel bar and an aluminum bar as shown in Figure: Q
3(a). Axial loads are applied at the positions indicated in the figure. Draw free body
diagram of each bar and find the value of P if overall deformation of the bar is 5.0 mm.
Assume that the bars are rigid enough to prevent buckling. Modulus of elasticity of steel,
aluminum and bronze are Esteel = 200 GPa, Ealum = 70 GPa, and Ebronz = 83 GPa
respectively.
