The elastic modulus is 40 GPa, the yield stress is 150 MPa, the ultimate stress is 525 MPa, and the ultimate strain is 0.38 (mm/mm). Perform the following tasks for this material.

1)What strain is realized if the material is stressed from 0 to 387 MPa?

2)Compute the tangent modulus between yield stress and ultimate stress.

3)If the stress then decreases from 387 MPa to 0 MPa, what is the permanent elongation if the original length of the brass specimen was 100 mm? 4)Assuming the coefficient of thermal expansion ? = 0.0000188 1/°C, what temperature change is required to return the 100-mm long specimen to 387MPa?
