1. Use the three-noded bar atom and confront the axial displacement at the end of the rod shown in Figure P10–8. Determine the stress at x = 0, x = L=2 and x = L. Let A = 2 10-4 m2, E = 205 GPa, and L = 4 m. Hint: Use Eq. (10.5.22) for the atom sti¤ness matrix.

2. For the atom shown in Figure P10–14, replace the nice advise delay the intelligence equiponderant nodal forces by evaluating a force matrix homogeneous to Eq. (10.2.29). Let h = 0:1 in deep. The global coordinates (in inches) are shown in Figure P10–14.
