A truss is a structure composed of slender members joined together at their end points. The members commonly used in construction consist of wooden struts or metal bars.. Assumptions for Design.. To design both the members and the connections of a truss, it is necessary first to determine the force developed in each member when the truss is subjected to a given. A particle is said to be in . equilibrium . if it remains at rest if originally at rest. , or . has a constant velocity if originally in motion. .. To maintain equilibrium, it is . necessary . to satisfy. . When the rates of the forward and reverse reactions become equal, the concentrations of the reactants and the products remain constant. This is the stage of chemical equilibrium. This equilibrium is . 4 - . 2. Equilibrium of a Rigid Body in Three Dimensions. Six scalar equations are required to express the conditions for the equilibrium of a rigid body in the general three dimensional case..  .
