Question

A hollow vertical cylinder of radius R is rotated with angular velocity w about an axis through
its center. What is the minimum coefficient of static friction necessary to keep the mass M
suspended on the inside of the cylinder as it rotates?
​

Answer 1

Answer:

THE CENTRIPETAL FORCE IS PROVIDED BY THE FRICTION FORCE.

FRICTION FORCE = CENTRIPETAL FORCE

$u \: mg = m {w}^{2}r \\ u = \frac{ {w}^{2} r}{g}$
