Part B - Calculate the elongation under load
A bar with a solid square cross-section is composed of three sections of equal length. The outer sections are made from material A and the middle section is made from material B, as shown in the figure. Assume the
stress-strain curves for the particular materials used are as shown. What is the change in the length of the bar if a tensile load of 88 kN is applied? The square cross-section has 2 cm sides and the length of each part
is 2 m. The elastic modulus of material A is 150 GPa and the elastic modulus of material B is 100 GPa
