Question
Determine the shear force acting at each of the following locations:
(a) x = 6.0-ft (i.e., just to the left of support B)
(b) x = 6.0+ ft (i.e., just to the right of support B)
(c) x = 25.5 ft
(d) x = 26.5-ft (i.e., just to the left of support C)
Note that x =0 at point A. When entering your answers, use the shear-force sign convention detailed in Section 7.2.

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 w = 20.0 kips/ft, a=6.0 ft, and b=20.5 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.
