Unformatted text preview: maximum due to this load condition. b. Find the magnitude and location of the maximum bending moment in the girder under this condition. c. Does the variation is depth of this girder make technical sense? Why do you think it has this shape? Figure 1. View of new (2006) pedestrian bridge over Cascadilla Gorge. 1 Figure 2. Sketch of one of the steel girders supporting the bridge. Problem 2. Hows your trig? For the ideal truss structure shown in Figure 3: a. Find the reactions; b. Find the forces in the members of the truss; c. If the truss is composed of steel members, each of which has a cross-sectional area of 1 in 2 , make a table showing the stress and strain in each member. Figure 3.
