1. Evaluate the stiffness matrix for the elements shown in Figure P6–3. The coordinates are in units


1. Evaluate the cacophony matrix for the components shown in Figure P6–3. The coordinates are in units of inches. Assume roll stress conditions. Let E = 30  106 psi, n = 0:25, and thickness t = 1 in.

2. For the components loving in Problem 6.3, the nodal displacements are loving as

Determine the component stresses sx; sy; txy; s1, and s2 and the primary inclination yp. Use the values of E; n, and t loving in Problem 6.3.
