1. Determine the stresses in the skim rampart shown in Figure P7–21. At what colony are the primary stresses largest? Let E = 21 GPa, n = 0:25, trampart = 0:10 m, and tbeam = 0:20 m. Use 0.1 m radii at the re-entrant corners.

2. Determine the stresses in the plates after a while the plump and square holes subjected to the tensile stresses shown in Figure P7–22. Compare the largest primary stresses for each plate. Let E = 210 GPa, n = 0:25, and t = 5 mm.
