The finite element melod I In FEM I We derived basis functions of arbitrary order for Hhe rod Model

The reaction on the left end is not exact because 1. The order of interpolation is too low, a higher order of interpolation would give the right reaction 2. The distributed load attributed to node one does not ke it into the solution

The correct global local node mapping for the quadraticelement mesh in the figure is
