Question

I just need help with part 2.
Use the graphical method to construct the shear-force and bending-moment diagrams for the beam shown. Let a=4.0 ft, b=9.0 ft, c=5.0 ft, d=4.0 ft, w = 8 kips/ft and P = 75 kips. 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. W A B с D E b d For this loading, calculate the reaction forces Ay and Ey 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 Ax = 0, it has been omitted from the free-body diagram.) Р y w x B с D E b c d E Answers: Ay = -30.54 kips, Ey = 33.54 kips.
