ralproducts in the last of these equations are to be determined fromthe data of the problem; but, in the case of equilibrium, it some-times is convenient to determine the signs from other considerationsless analytical. Let us suppose the origin of the axes A (fig. 46),which we have taken for the… … EQUILIBRIUM OF A SOLID BODY. 77 iug at rest the point A will be at rest, and may, therefore, be con-sidered as fixed. Now the tendency of the forces P, P^^, P^, asmarked in the figure, is to make the extremities oi p, p^, p^, onwhich they act, to tiirn round A in the same direction, and,…
