2. The square plate is fixed at the edge CD and free at the edge AB. It is subjected to uniformly distributed force q=1 on the edge AB. Please write a program to solve this problem by using 2D element and analyze the in-plane displacement and stress of the plate. Write a program by using MATLAB, Visual C, and Fortran etc. Requirement: (1) Use two meshes: (a) 10*10, (b) 50*50; (2) find out the maximum values of displacement and stress; (3) Draw deformation graph for static analysis.
