Designing bridge not perpendicular with ground

  1. Jan 28, 2016 #1
    I was wondering how to approach building a bridge which must lie across to points of differing points (one end is elevated 5 cm off the ground), meaning the bridge lies at an angle across a 35cm expanse. How would you calculate the forces exerted on each member if the bridge does not lie perpendicular with the ground? Thanks!

    Welcome to the PF.

    I think you mean to ask about the case where the bridge is not "parallel" to the ground, rather than "perpendicular" to the ground, right? :smile:

    What is the context of the question? You are using small dimensions in your question, so I'm assuming that this is a small/scale model of a bridge? Is this for a schoolwork project?
