For the simply supported beam subjected to the loading shown, derive equations for the shear force V and the bending moment Mfor any location in the beam. (Place the origin at point A.) Let a=1.50 m, b=6.00 m, PA = 70kN, and Pc = 50kn. Construct the shear-force and bending-moment diagrams on paper and use the results to answer the questions in the subsequent parts of this GO exercise. . Pc x D b q Calculate the reaction forces By and Dy acting on the beam. Positive values for the reactions are indicated by the directions of the red arrows shown on the free-body diagram below. (Note: Since Bx = 0, it has been omitted from the free-body diagram.) PA Pc B q D Answers: BY KN Dy = KN
