The formula for the centrifugalforce may be found in any treatise on Mechanics, and is asfollows: , MrJ ~ ? in which / is the centrifugal force, r theradius of the circle of revolution, and t theperiodic time, or the time in which… … 66 DENTRIFUGAI FORCE. solar day, and therefore contains 86,101s. Substituting thisvalue of t in the formula given above, and substituting for r thevalue of the earths equatorial radius in feet, and computingthe value of/, we shall find that the centrifugal-force at theequator is .1113 feet. Now the…
