1. Evaluate the outline functions for the linear-strain triangle shown in Figure P8–7. Then evaluate the =B matrix. Units are millimeters.

2. For the parts shown in Figure P9–1, evaluate the slang matrices using Eq. (9.2.2). The coordinates are shown in the figures. Let E = 30  106 psi and n = 0:25 for each part.
