3 (15 points) A bent circular cantilever beam of uniform diameter of 25 mm is shown in igure below. The beam is made from a material with elastic modulus is 70 GPa, the tensile strength is 250 M...
The cylindrical pressure vessel shown in the figure has an inside diameter of 980 mm and a wall thickness of 12 mm. The cylinder is made of an aluminum alloy that has an elastic modulus of E = 72 GPa and a shear modulus of G = 27.5 GPa. Two strain gages are mounted on the exterior surface of the cylinder at right angles to each other. The angle θ is 21°. If the pressure in the vessel is 1.86...
6.1 A simply supported laminated composite beam (Figure 6.6) made of glass/epoxy is 75 mm long and has the layup of [±30]2s. A uniform load is applied on the beam that is 5 mm in width. Assume each ply is 0.125 mm thick and the properties of glass/epoxy are from Table 2.1. 1. What is the maximum deflection of the beam? 2. Find the local stresses at the top of the laminate. q- 100 N/m 0.075 m FIGURE 6.6 Uniformly...
