The steel (E = 200GPa, v=0.32) vertical post is loaded to the forces as shown in Figure Q1. If the strain gauges a and b are firmly attached at point A give readings of & - 300μ and = 175μ. Determine the magnitudes of P, assuming that P = P2. There is no transverse force occurs at point A. Solve the following problems: (a) Sketch the free body diagram at point A, (b) Find the moment of inertia of the cross section, (c) Find the normal strains at point A, and (d) Find force P₁. 60 cm 2.5 cm 10 cm 2.5 cm Section e-c 5 cm
