Question details

MECHANICS OF MATERIALS: ENGR 2070-SPRING 2019 ASSIGNMENT PkN 5. Determine the internal normal forces in members BC, FC, and FE of the truss shown, in terms of the applied force P. Assume all members are pin-connected. Clearly state if these members are in tension (T) or compression (C). (Note: Remember that two-force members cut perpendicular to their longitudinal axis (which we assume to be the case unless told otherwise) have zero internal shear force and zero internal moment, leaving only internal normal force to potentially be nonzero. Also, for two-force members, their state of tension/compression is usually reported, rather than reporting signs as we normally do for internal loadings. (However, if a sign is given, usually positive is associated with tension, and negative is associated with compression.) Pk
