eight of the pendulum may be resolved into two compo,-nents, one of which, F, acts in the direction of the motion of thependulum, Avhile the other, P, acts at right angles to this direc-tion, that is, in the direction of the length of the thread. Theformer component, F, acting at each point in the… … THE PENDULUM. Since the force F, which produces themotion, is- always a component of theweight mg, it is clear, Fig. 96, that F ■ . = sin ^ m (/ or I = rn (J sin ^, where B is the angle through which thependulum has been displaced from its po-sition of equilibrium. If the angle (9through which the…
