B. Three high-strength concrete poles, with an effective cross-sectional area of 40,000 mm? and a length of 2 m, support a stiff steel plate. The center post is 1 mm shorter than the others before the load P is applied. If the concrete's allowed compressive stress is 20 MPa, calculate the maximum load that can be carried. E = 30 GPa for P %3D concrete.
