- If it is constrained between two supports A and B and is stress-free at 20 ℃, what would be the stress in the two materials when it is heated to 70 ℃, For Steel: Es = 210 GPa, Coefficient of expansion = 12x10^6/℃. For Brass: Eb = 105 GPa, Coefficient of expansion = 19x10^-6/℃arrow_forwardA steel bar is connected to an aluminum bar as shown below. At 70 F, the stresses in the steel and the aluminum bars are zero. Calculate the stresses in the steel and in the aluminum when the temperature rises to 120 F. Indicate whether the stresses are tensile or compressive. The properties of the steel and the aluminum are given below. The cross-sectional areas of the steel and the aluminum are the same.arrow_forwardA copper rod is deformed using a uniaxial tensile force of 16000 N. Deformation continues until sufficient strain hardening has occurred such that the applied force is too small to allow further deformation. After deformation, the rod has a diameter of 0.01 m and a length of 1.5 m. Assume that copper follows the strain hardening lawwith K of 310 MPa and n=0.54 Please calculate the true strain after the deformation ?arrow_forward
