Consider again Example 12-11 but this time assume
Chapter 12, Problem 12.52(choose chapter or problem)
Consider again Example 12-11 but this time assume theroadway is supported uniformly so that \ its mass M(= 7.0 X 105 kg) acts at the center and \ M at each end support(think of the bridge as two spans, AC and CE, so the centerpin supports two span ends). Calculate the magnitude of theforce in each truss member and compare to Example 12-11.
