A cube with a side of a=15 cm is seated in a rigid recess from its five faces, as shown in the figure. The free face is subjected to a stress of P= 80 MPa. Find the change in length of the cube. Calculate the compressive stresses at the edges.
Note: The top figure is the side view, the bottom figure is the top view of the system. E=40 GPa will be taken.
