a).Construct a moment diagram. First, we compute the values of the bending moment at sev-eral sections; thus, M^=-500 X1-100 X i=-550 foot-pounda,M3=-500 X 2-200 X1=-1,200,M3=-500 X 3-1,000 X1-300 X li=-2,950,M^=-500 X 4-1,000 X 2-400 X 2=-4,800,M^=-500 X 5-1,000 X 3-500 X 2i=—6,750,M^=-500 X… … Sca>Je: f = 2oooof t.-lb3 Fig. 20.These values all beincr negative, the ordinates are all laid offdownwards.
