The rectangular steel (E = 30 × 106 psi, ν = 0.30)
plate in Figure 11.39 is 0.25 in thick and is loaded with an axial stress of
400 psi. Use two triangular plane stress elements to approximate the
deflections at the end of the plate subjected to the applied load. Assume one
node at the fixed end is on rollers. Hand calculations are to be used.
