Main Question or Discussion Point
Hi all, I've been looking at a few trusses lately and was wondering what the main factors are that influence the overall strength of a truss bridge? I have an idea that the more members taking loads, the stronger the truss, hence members should be at sharper angles. Of course i could be dead wrong, perhaps certain angles allow a better distribution of loads through all members thus allowing a greater overall load to be placed on a truss bridge? I Am looking at point-loads specifically but would be interested in moving loads as well.
