Part 4 Use your shear-force and bending-moment diagrams to determine the maximum positive bending moment, Mmax, pos; the maximum negative bending moment, Mmax, neg, and their respective locations, Xmax, pos and Xmax, neg. Use the bending-moment sign convention detailed in Section 7.2. The maximum negative bending moment is the negative moment with the largest absolute value. Enter the maximum negative bending moment as a negative value. Answers: Mmax, pos Mmax, neg = i i kips-ft,, Xmax, pos = kips-ft, Xmax, neg i i ft ft

Part 1
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 = 19.5 kips/ft, a=7.0 ft, and b=18.0 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.
