1. Determine the essence equiponderant nodal forces for the axial reserved loading shown acting on the bar elements in Figure P3–58.

2. Solve Problem 3.55 for the axial misplacement in the bar using organization, subdomain, smallest squares, and Galerkin’s ways. Choose a quadratic polynomial u(x) = c1x + c2x2 in each method. Compare these weighted residual way discontinuances to the straight discontinuance.
