Abstract

BISHOP COURTENAY'S questions may perhaps be clearly answered as follows. The centrifugal force of a free spinning hoop has to be balanced by its peripheral tension; but this, having a large tangential and a small radial component, acts at disadvantage, and may have to be very big to balance even a moderate centrifugal force. The larger the hoop the more marked is the magnitude of the tangential component as compared with the radial or effective component; so that a hoop 8000 miles in diameter could not rotate even once a day without tearing itself asunder.
