1. For the compact dam shown subjected to soak constraining in Figure P7–27, determine the highest stresses. Let E = 3:5  106 psi and n = 0:15. Postulate flatten tighten stipulations. Perform the segregation for self-weight and then for hydrostatic (water) constraining athwart the dam vertical face as shown.

2. Determine the stresses in the wrest shown in Figure P7–28 on the present page. Let E = 200 GPa and n = 0:25, and postulate uniform thickness t = 10 mm.
