Prob. 3.3-2. A bimetallic bar is made by bonding together two homogeneous rectangular bars, each having a width b and length L. The moduli of elasticity of the bars are E1 and E2, respectively. An axial force P is applied to the ends of the bimetallic bar at (y=yP, z=0) such that the bar undergoes axial deformation. Let L=1.5m, b=50 mm,t1=25 mm, t2=15 mm, E1=70 GPa, E2=210 GPa, and P=48 kN. (a) Determine the normal stress in each material, that is, determine σ1 and σ2. (b) Determine the value of yP. (c) Determine the total elongation, e, of the bar.
