1. A simply supported beam with length L is under a uniformly distributed load — p. When two equal-length beam elements are used, the finite element analysis yields the following nodal DOFs:

{1Q ,J}T =1 { f'l ,,'0 '1 ', 1\ )2' ,2024, El>3I ,3038} 4= 7(0?,-/^ ,-' ^',20,40,£-^/-J1.

Find the deflection curve v(x) and compare graphically with the exact solution. Note: the exact deflection curve of the beam is given as fexactM = ~P(x4 ~ 2Lx3 + L3x)/2AEI.
