If G is the centre of mass of the remaining material,</p> <p> find(i) the distance PG, </p> <p>and (ii) the radius of gyration of the remaining material about a common tangent at P to the spherical surfaces.</p> <br class="clear" /> http://imechanica.org/node/877#comments Ask iMechanica Mon, 19 Feb 2007 14:26:27 -0500 jngf 877 at http://imechanica.org
