How do you solve the following trusses without given lengths? Can you help me? There are three trusses in total, one that is a symmetrical roof truss, another is the house shaped truss and the last one is the slide-like truss. I am finding it difficult to compute for axial forces required (the members which have numbers on them) since they don't have given lengths. Is it possible to compute the forces of these members?

Symmetrical Roof Truss In order to solve this truss we must first identify the forces acting on each member by analyzing the loading conditions The symmetrical roof truss is made up of two identical s... View the full answer
