Rotational Dynamics

Mass Moment Inertia


<div class="wp-block-create-block-problemblock">A solid brass sphere of mass m and radius r << R rolls along a track when released from rest along the straight section.  The circular loop has a radius R.<br /><img src="/old/images/brainpuzzles.gif"  alt="brain puzzles IQ tests ><br />A. What is h in terms of R if the sphere is on the verge of leaving the track when it reaches the top of the loop? <br">B. Assume the sphere is released at height h = 6.0 R, what are the magnitude and direction of the horizontal force competent acting on the sphere at point Q?</div>
