If a structure is statically determinate, i.e., DSI=0, then it suffices to use equilibrium to determine the section forces. In fact, this is the fundamental definition of DSI: Any nonzero degree of indeterminacy means that there are too many unknown forces for us to determine the section forces by equilibrium. fit firm and fabulous scam
