[[upper right hand corner]](302 perpendicular to EQ; then per mech. t+1: p over T+1 squared::1:p over T+1 squared multiplied by t+1 equals ET, the pressure upon A, which substraited from E6, leaves PT over T+1 squared multiplied by t+1 equal to Et, the power with which the plane endeavours to move in the direction EB. 4. Since the plane PEL can only move in a circle round A, EB is an imaginary direction; and therefore this power Et, must be reduced to the direction EQ, perpendicular to EA; whence, per mech. 1: t+1 :: pt over T+1 squared multiplied by t+1 : pt over T+1 squared equals Et+td equals EQ, a general theorem for the power acting against the plane PEL, in the direction QE to sustain the whole in equilibrio. Q.E.F. Cor. 1. As the distances of A and C from E are not concerned, they may be assumed at pleasure, so that A is perpendicularly over C. Cor. 2. It appears that the less T is in respect to t, the greater will the effect EQ be upon the rod of the pendulum. Example Suppose the [[angle symbol]] CEL=59 1/2 degrees and AEL=51 1/2 degrees, (as I measured them in Ludlam's figure) and the tooth E endued with a power equal to 6 Ounces.
