A structural support for a machine will be subjected to a static tensile load of 16.0 kN. It is planned to fabricate the support from a square rod made from SAE 1020 hot-rolled steel. Specify suitable dimensions for the cross section of the rod.

450 mm long a ISI 1020 Steel long is subjected to a tensile load of 55 kilo Newton the allowable tensile stress is 140 mega pascal and the allowable total elongation is not to exit 0.2 mm calculate the required rod diameter the proportional limit is 175 megapascal

Hi, Could i please have the answrs, workings out anf formulas ues for the attached question.   Thank you.

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.

Problem parameters for Case #2: Cases Load (lbs) 2 55,000 What is the total Deformation in (in) on the rod? Note: • Give your answer rounded to 3 decimal place i.e. 0.04352 = 0.044 or 0.04342 = 0.043 • Do NOT include any units or other text. The size of your numeric value should be given in (in). i.e. if your answer is 0.043 (in) then enter this as "0.043" (Do NOT enter "0.043 in")

Design a helical compression spring for a maximum load of 1000 N for a deflection of 25 mm using the value of spring index as 5. The operating load is considered as average load service. Choose a suitable material from table (23.1) for your design. If the same helical compression spring that was designed in Q1, is subjected to a load which vary from 200 N to 600 N. Based on the new condition, will the spring endure the new load? Consider that the allowable shear stress in table (23.1) is the yield stress and the endurance shear stress is 0.8 to 0.9 of the yield in shear. mechanical desgin pls solve fast
