Transcribed Image Text:Part 1
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-10.5 ft, b-24.0 ft, P- 20 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.
B
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 A, - 0, it has been omitted from the free-body diagram.)
Answers:
kips
Cy-
kips
Part 2

(a) x = 10.5-ft (i.e., just to the left of point B)
(b) x = 10.5+ ft (i.e., just to the right of point B)
(c) x = 32.5 ft
Note that x-0 at support A. When entering your answers, use the shear-force sign convention detailed in Section 7.2.
Answers:
