CEE/ME 241 2 APPLICATIONS For a given load on the platform, how can we determine the forces at the joint A and the force in the link (cylinder) BC? APPLICATIONS (continued) A steel beam is used to support roof joists. How can we determine the support reactions at each end of the beam?
CEE/ME 241 3 EQUATIONS OF EQUILIBRIUM (Section 5.3) A body is subjected to a system of forces that lie in the x-y plane. When in equilibrium, the net force and net moment acting on the body are zero (as discussed earlier in Section 5.1). This 2-D condition can be represented by the three scalar equations: F x = 0 F y = 0 M O = 0 Where point O is any arbitrary point.
