For the simply supported beam subjected to the loading shown, derive equations for the shear force V and the bending moment M for any location in the beam. (Place the origin at point A.) Let a=8.5 ft, b=24.0 ft, P = 30 kips and w = 5.5 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.



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.)

Determine the shear force acting at each of the following locations:

(a) x = 8.5- ft (i.e., just to the left of point B)
(b) x = 8.5+ ft (i.e., just to the right of point B)
(c) x = 30.5 ft
Note that = 0 at support A.  When entering your answers, use the shear-force sign convention detailed in Section 7.2.

Determine the bending moment acting at each of the following locations:

(a) x = 8.5 ft (i.e., at point B)
(b) x = 30.5 ft

Note that x = 0 at support A. When entering your answers, use the bending-moment sign convention detailed in Section 7.2.

 

Use your shear-force and bending-moment diagrams to determine the maximum bending moment, Mmax, and its location, xmax. Use the bending-moment sign convention detailed in Section 7.2.
