Given the weight of a CL-625 design truck (625 kN) on a truss bridge of span 50m, divided into 8 sections (each 6.25 m) with a height of 6.25m making 45deg angles and a width of 6m, what are the tension and compression forces of the members?
Mb = PL/4
The Attempt at a Solution
Using these equations, I got a total tension of 625kN.. I don't know if I'm using the equations wrong or I'm missing something completely, but that seems like a very small number.
