Question

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

(a) x = 12.0- ft (i.e., just to the left of point B)
(b) x = 12.0+ ft (i.e., just to the right of point B)
(c) x = 31.0 ft
Note that x = 0 at support A. When entering your answers, use the shear-force sign convention detailed in Section 7.2.

Answers:

(a)	V =	kips
(b)	V =	kips
(c)	V =	kips

For the simply supported beam subjected to the loading shown, derive equations for the shear force Vand the bending moment M
for any location in the beam. (Place the origin at point A.) Let a=12.0 ft, b=21.0 ft, P = 20 kips and w = 8.5 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.
