1. The problem statement, all variables and given/known data 2. Relevant equations * If the only members of an unloaded joint are two noncollinear members, both members are zero-force members. * If an unloaded joint has two collinear members and one noncollinear member only, the noncollinear member is a zero-force member. 3. The attempt at a solution i cant seem to grasp this idea. would BE be the only zero force member? Even then i dont understand because BE would have the Force P heading towards it in the x direction wouldn't it?
