Use the graphical method to construct the shear-force and bending-moment diagrams for the beam shown. Let a=2 ft, b=7 ft, c=3 ft and w=7.5 kips/ft. 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 B D b a C Calculate the reaction forces Ay and Cy 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.) W ·x B C-A kips. a Answers: Ay= b C C₂ kips, Cy= i
Determine the shear force acting at each of the following locations: (a) x = 0+ ft (i.e., just to the right of support A) (b) x = 2 ft (c) x = 9-ft (i.e., just to the left of support C) (d) x = 9+ ft (i.e., just to the right of support C) When entering your answers, use the shear force sign convention. Answers: (a) V = i kips. (b) V = i kips. (c) V = i kips. (d) V= kips. M
Use the graphical method to determine the bending moment acting at B (i.e., x = 2 ft). When entering your answers, use the bending moment sign convention. Answer: Mg = i kip-ft. eTextbook and Media Save for Later Attempts: unlimited Submit Answer Part 4 The shear-force diagram crosses the V = 0 axis between points B and C. Determine the location x (measured from A) where V = 0 kips. Answer: x = i ft.
Consider the entire beam and determine: (a) the maximum positive bending moment. (b) the maximum negative bending moment. When entering your answers, use the bending moment sign convention. Answers: (a) M = i kip-ft. (b) M = i kip-ft.
