- There is a tube from aluminium, which has an outside diameter of 50 (mm) and a wall thickness of 5 (mm) is used as a compression member. If the axial normal stress in the member must be limited to 90 MPa, what can the maximum force (in kN) that the member can support?arrow_forwardA 1.25 inch diameter hole is drilled on the centerline of a steel bar 3.5 inches wide by 3/8 inches thick. Calculate the maximum load that can be applied to the bar without exceeding the maximum stress in the bar of 22,000 psi.arrow_forwardPlease help me understand this solution. I want to know how the stress in concrete was solved for. I don't quite understand beyond part ii). Attached is the problem and the solution This is the problem: The figure shows the cross section of a circular steel tube that is filled with concrete and topped with a rigid cap. Calculate the stresses in the steel and in the concrete caused by the 200-kip axial load. Use Est = 29 x 106 psi and Eco = 3.5 x 106 psi.arrow_forward

Calculate the bearing stress and shear stress between the pin and each bracket of a clevis joint. Assume pin diameter of 10 mm, 40 mm wide gap link, 12 mm thick bracket, and 3550N tensile load. Draw a free body diagram (geometry & forces) Identify stress plane Calculate stress and write it (with appropriate units) in the outlined boxarrow_forwardYou are required to size member FI of the truss shown at right using Western lumber with the following properties:• Yield stress in compression: 2100 psi• Yield stress in tension: 1300 psi• Modulus of elasticity 1700 ksi.Use a factor of safety of 2.0. For the selected section:c. Calculate the stress and the strain in member FId. Calculate the deflection of member FI; specify if elongation or shortening.arrow_forward
- A 3-in. by 6-in. steel (E-29,000 ksi) bar (4-foot long) is subjected to the loads shown. Calculate the combined stresses at points A and B (be sure to indicate either tension or compression). Remember, the bar is bending in the strong direction so calculate your I accordingly. 1(1/12) (B)"(H) S=l/c A B. 6" 10,000 lbs 45,000 Ibsarrow_forwardPRELIMINARY DISCUSSIONS PME 412 - MACHINE DESIGN 1 PROBLEM: Find the values and plot the distribution of stress over the cross section of the upright of the figure.
