A rigid steel plate is supported by three posts of high-strength concrete each having an effective cross-sectional area A-40,000 mm2 and length L-2 m (see figurel. Before the load Pis applied, the middle post is shorter than the others by an amount s-1.0 mm. The allowable compressive stress in the concrete is 20 MPa and E of concrete is 30 GPa Determine the axial deformation in mm of the outer posts when the axial stresses reached the allowable compressive stress of 20 MPa. 2 decimah)
