5 (20%) A traction Tx = 10 kN/m is applied at the top of the plane problem shown, with the bottom side is fixed and the top side is only

allowed to move horizontally. E = 10GPAand v = 0.25. Use one plane element to calculate the stress and strain components for the case of (a) thickness t = 0.1 m and (b) thickness t = 10 m.
