Need help with this review stuck on part C

Engineering of Materials

 

 

Hooke's Law 7 of 8 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 o (MPa) 400 Material A 300 Material B 200 Material A 100 0.002 0.004 0.006 Express your answer to three significant figures in meters. • View Available Hint(s) 1.15x10-2 m Submit Previous Answers Correct
