ached to the pulley, the tension of each ropeis ^. Let c, a, and 6 be the radii of the cylinders, beginning with thelargest. Taking moments about the axis, we have Pc+ f- w W 2c • • P~ a-h By making a and 6 nearly equal we can get a large mechanicaladvantage. Ex. In the differential wheel and axle,… … Fig. 124. CO OC is a strong frame. In CO a groove is cut in which thethread of the screw on AD works, AD is hollow and the solid screwDE works inside it. To the lower screw a board is attached which is guided to work upand down by smooth vertical grooves cut in CG, thus the lower screwcan move up…
