Solve Problem by using a computer program.

Solve the grid structures shown in Figures P5–52 through P5–57 using a computer program. For grids except as noted in the figures. In Figure P5–54, let the cross elements

have with dimensions and loads as in Figure. For grids P5–55 through P5–57, let E = 210 GPa, G = 84 GPa,
