is, in order that a body with a certain velocity may move in a circle, it must be drawn tothe centre by a force which is directly as the squareof the velocity with which the body moves, and whichis inversely as the radius of the circle. In order toexpress this in the ordinary units of weight, we… … stantly neutralised by the centrifugal force. The above expression may be put in a form whichis sometimes more convenient. If T be the time inseconds required to traverse the circumference 2nr with the velocity v, then v- = ^^-, from which P ^4W7rV^4W7rV Fig. 35. If a rigid body rotates about a…
