A 10-mm-thick, low-alloy-steel plate 180 mm wide and 2000 mm long is subjected to a set of uniformly distributed frictional forces along its two edges, as shown in the figure. If the total decrease in the transverse 180-mm dimension at section a--a due to the applied forces is 16 x 10 mm, what is the total elongation of the bar in the longitudinal direction? Let E= 200 GPa and v= 0.25. Assume that the steel behaves as a linearly elastic material
