Remember it has to be in meters for part B and C please they are linked
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 Bis 100 GPa. o (MPa 400 Material A 300 Material B 200 Material A 100 0.002 0.004 O 006 Express your answer to three significant figures in meters. • View Available Hint(s) V AEd Submit Previous Answers Request Answer X Incorrect; Try Again; 2 attempts remaining Part C- Hooke's law and strain hardening When the bar in Part B is unloaded, it will have a permanent change in length.
