Uniplanar Systems ofForces.—As conducive to clearness in subsequent matter, therigid bodies composing a structure will be named according tothe number of forces acting on each ; and these forces consist ofgravity actions (i.e., weights) and of the pressures exerted byneighboring pieces on the piece… … centre of gravity. (Of course, the action of gravity is distributedover all the particles of a body, but the above-mentioned singleforce is the full equivalent of these distributed forces as far asthe equilihrium of the piece is concerned; though not such as re-gards the straining action on the…
