s and values of the severalproducts 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.

Now the tendency of the forces P, P^, P^, asmarked in the figure, is to make the extremities of p, p^, p^, onwhich they act, to turn round A in the same direction, and,…
