1. A tensile load of 5.00 kN is applied to a square bar 12 mm on a side and having a length of 1.65 m.
(a) Compute the stress and the axial deformation in the bar if it is made from (i) SAE 1020 hot-
rolled steel, (ii) SAE 8650 OQT 1000 steel, (iii) ductile iron A536(60-40-18), (iv) aluminum
6061-T6, (v) titanium Ti-6Al-4V, (vi) rigid PVC plastic, and (vii) phenolic plastic.
(b) For each of the case in (a), compute the maximum safe load that can be carried by the bar.
450-mm-long AISI 1020 steel rod is subjected to a tensile load of 55 kN. The allowable tensile stress is 140 MPa and the allowable total elongation is not to exceed 0.2 mm. Calculate the required rod diameter. The proportional limit is 175 MPa.
Two links are connected by a single pin and a tensile force F is applied. The links and the pin are made from Aluminum(sigma_y = 35ksi and T_y = 20ksi). The dimension of the link is 5 inch high by 0.5 inch thick. Find the optimal diameter for the pin and the maximum force,F that can be applied to the linkage before incuring permanent deformation.
