Find the stresses by finite method, Mechanical Engineering

The stepped bar in Fig Q6 is stretched along the vertical axis and the maximum upward displacement is found to be 0.008 m. The bar has cross-sectional areas of A1 and A2 over the lengths L1 and L2, respectively. Using the data below, find the stresses induced in the axially loaded stepped bar by the finite element method through hand calculations.

 A1=0.0002 m2, A2=0.0008 m2; L1= 1 m L2= 2 m; E1=ABCDE MPa, E2=20000MPa
