· There are two basic balances that must exist in any statics problems.
· if the sum of the forces is not zero, then the system will undergo translation, and the problem cannot be solved with statics methods.
· if the sum of moments is not zero, then the system will undergo rotation, and the problem cannot be solved with statics methods.
· At least one of these two equations will appear in every statics problem.
· Let's consider a force balance problem, ([Hibbeler, 1992]prob 3-40, pg. )
