otion which is the resultant of two motions, the resultant along any line of the forces acting upon the body and causing or controlling its motion is found by adding the components, along the same line, of the forces causing or controlling the two component motions taken separately. In other words:… … Let the radius of the fixed circle Fig. 2. be rv of the rolling circle r2. We have from kinematics that c = a + b, and the triple proportion (0 a : b : c = r2 : r, : r, + r. Let the center of mass be at P, a distance nr2 from the center C , and let / be the instantaneous axis of the moving circle.…
