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 figure). 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. What is the axial deformation in mm of the outer posts when the gap was just closed? (4 decimals)
