Problem 9Analyze the two-beam structure depicted in Figure 9.1. Both beams are clamped at the ends. Figure 9.2 shows the loads acting on the structure. Consider a value of E=30x10. psi and a value of . =.333. Determine the deformed shape of the structure, the reactions, and the forces and moments in the beams.

Problem 11Consider the plate shown in Figure 11.1. It is clamped on one edge and supported at two points, (x=200 in, y=0 in) and (x=200 in, y=100 in). A load of 100 lb is applied at (x=200 in, y=50 in) in the negative z-direction. Determine the plate forces, stresses, and reactions at the supports. Assume E=30xl0. psi and . =.33.

Problem 12Consider a thin steel sheet as shown in Figure 12.1. Determine the stresses on this sheet if the right edge is pulled with a force of 240,000 N distributed uniformly along the edge. Use a value of E equal to 200,000 N/mm. and a Poisson’s ratio of 0.333.

Problem 13Consider the solid block described in Figure 13.1. It is made of concrete and it is loaded with a uniform pressure of 100 Kilos per square meter (K/m.) on the top surface. Determine the stresses in the block and the foundation reactions due to this load. Assume E=2.5x10. K/m. and .=0.25 for concrete.
