e magnitude of the force which must be exerted parallel \.o A B xn. order to put the body in equilibrium—i. e., to balance the force which gravity exerts in pulling the body down the plane. If the rope r were parallel to A B, a c would represent the weight of P; but, since r makes an angle with the… … treat ad zs though it were a compo-nent of the force acting in the rope—i. e., draw de perpendicular to ad, in-stead of perpendicular to a e. Thereason for this is that if d e weredrawn perpendicular to a e it couldbe resolved into components, one ofwhich would be parallel to a d, a re-sult which…
