PASSAGE
A Fink roof truss is modeled as a statically determinate planar truss. An analyst applies the method of sections and cuts through exactly three members, but upon examining the free-body diagram of the isolated portion, discovers that two of the three cut members are zero-force members under the given loading.
Given that two of the three cut members carry zero force, what is the most rigorous statement about the analyst's ability to determine the force in the remaining (non-zero) cut member using the method of sections on this free-body alone?
