- I need the answer as soon as possiblearrow_forwardThe composite bar shown in the figure is firmly attached to unyielding supports. An Axial force P = 52 kips is applied at 65°F. Compute the stress (ksi) in the Aluminum at 116 °F. Assume a = 6.5 x 10-6/° F for steel and 12.8 x 106/°F for aluminum Given: L1 = 15in; L2 = 11in Your final answer should contain two decimal places Steel A = 3 in² E = 29 x 106 psi Correct Answer: 3.92 L2 Aluminum A = 2 in² E = 10 x 106 psi L1arrow_forwardDetermine the compressive force (in lb) in the bars shown after a temperature rise of 173°F if d = 0.015 in. Round off the final answer to five decimal places. Use the following data: Bronze Aluminum A = 2.24 sq. in A = 2.78 sq. in E = 14959726 psi E = 10594540 psi L = 12.5 in L = 16.6 in α = 11.61 x 10-6/ °F α = 12.67 x 10-6/°Farrow_forward
- Problem 6arrow_forwardSketch the stress-strain curve and explain it in relation to the tensile test for steel bars.arrow_forwardPLEASE WRITE YOUR COMPLETE SOLUTION AND BOX THE FINAL ANSWER. THANK YOU. A series of rigidly attached aluminum bars carries the axial loads at the positions shown. If the modulus of elasticity E = 16×10^6 psi, compute the total deformation of the bar and state if the bar elongates or shortens. Assume that the bar is suitably braced to prevent lateral buckling.arrow_forward
