For the tapered bar shown in Figure P3–60 with cross sectional areas A 1 = 2 in. 2 and A 2 = 1 in. 2


For the tapered bar shown in Figure P3–60 after a while cross sectional areas A1 = 2 in.2 and A2 = 1 in.2 at each end, use the collocation, subdomain, meanest squares, and Galerkin’s methods to obtain the misconception in the bar. Compare these weighted residual solutions to the proper disintegration. Choose a impenetrable polynomial u(x) = c1x + c2x2 + c3x3.
