gether disregard the motion of the wheel producedby the radial motion of the point. Considering again the differential of area of Fig. 49, it isseen that the motion of the tracing point from 4 to 5 is greaterthan that from 6 to 7, and that the angle made by the arms isdifferent when the point… … 14 PLANIMETERS 79 See Fig. 50. The record wheel moves from 2 to 2 when thetracing point passes from 4 to 5. The rectangular componentof the motion, 2-2, causing rotation of the wheel, is representedby the line m, perpendicular to the wheel axis, m is therefore
