of Power may be found in any Inclination of the 
Plane. Thus, as here, the Power, which in the 
common Way wou’d be but t of the Weight, muft 
be j Part of it : So if the Angle of the Plane’s Incli* 
nation was but 31' the Power would be i of the 
Weight, (fc.

Hence follows alfo, that- if the Plane B E be Hori- 
zontal, no Force of the Power will be loft, becaufe

As the Fridion of the winding of the Ropes, fuch 
as B ^7 in the new Way, is greater than the Fridion 
of the Pivot in the old Way (belides the Fridion of 
the Collars of the Counterpoife to the Engine) fo that 
Fridion diminifhes, as the Ropes bear lefs Weight, ac- 
cording to the Diminution of the Angle of the Plane , 
and when the Plane is horizontal, and without a Coun- 
terpoife, even then the winding up of the Ropes, and 
Prefture of the Roller againft the Plane, is equal to 
the Fridion in the common Way. 
N.B. The Experiment is made here with Pivots 
twelve times lefs in Diameter than the Roller, and fine 
pliable Silk, inftead of Ropes.
