Q3 The plane stress distribution in a flat plate of unit thickness is given by: =yx-2axy + by = xy-2xy 3 x + ay ++c Show that, in the absence of body forces, equilibrium exists. The load on the plate is specified by the following boundary conditions: W At x=- = 0 At x 2 2x=0 Where w is the width of the plate. If the length of the plate is L, determine the values of the constants a, b,and c and determine the total load on the edge of the plate, x = w/2.
