General Systems of Forces, Equilibrium of a Rigid Body,equilibrium. They should also learn how to apply the method of sections to obtain a free-body diagram. A correct free-body diagram and an appropriate application of the equilibrium conditions are the key to the solution of a coplanar or a spatial problem.

Introduction,s its range of application grows. The tasks of mechanics include the description and determination of the motion of bodies, as well as the investigation of the forces associated with the motion. Technical examples of such motions are the rolling wheel of a vehicle, the flow of a fluid in a duct, the

Basic Concepts,ms, formulas, and work principles. Of particular importance are the “method of sections”, the “l(fā)aw of action and reaction”, and the “free-body diagram”, as they are used to solve nearly all problems in statics. The concept of . can be taken from our daily experience. Although forces cannot be seen o

Forces with a Common Point of Application,lways act on a body; there are no forces without action on a body. In the case of a rigid body, the forces acting on it do not have to have the same point of application; it is sufficient that their lines of action intersect at a common point. Since in this case the force vectors are sliding vectors
