For checking static determinacy, indeterminacy and stability of truss. if m + R = 2j then, truss is stable. if m + R > 2j then, truss is indeterminate Websuitable for analysing it. 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. cryptic-sounding
