1.If the only members of an unloaded joint are two noncollinear members, both members are zero-force members.2.If an unloaded joint has two collinear members and one noncollinear member only, the noncollinear member is a zero-force member.Does that help?
For the truss shown, find: a) all zero force members b) using the method of joints determine the forces in all the members to the left of member EL c) using the method of sections determine the forces in EF, FL, and LM. Indicate whether the member...
Zero-force members are members that are not affected by the applied forces. Here are the two cases to consider when looking for a zero-force member in a truss. Case 1. When two members are connected by a joint and there are no forces acting on that jo...
