AC = Pj.CB. 37. Def. When AB is perpendicular to the direction of theforces, AC and BC are called the arms of the forces, and theproducts P.AC and P,.CB are the moments of the forces aboutthe point C. 38. Cor. If to the point C we apply a force R,, equal andopposite to R, the forces P, Pj, and Rj… … PARALLEL FORCES. 17 direction of the forces, calling the parts intercepted by P andPj respectively p and px ; from the similar triangles, thusformed, we should have BC:CA=^, :p..: PiP^p, :p, or P.jp=P1p1. Hence the moments of P and Pa, which measure the tendencyto rotation in opposite directions,…
