A centrifuge is used to separate liquids according to their densities using centrifugal force. Figure illustrates one arm of a centrifuge having a bucket at its end to hold the liquid. In operation, the bucket and the liquid have a mass of 0.40 kg. The centrifugal force has the magnitude in newtons of F= 0.010 91-m-R-n2

where m — rotating mass of bucket and liquid (kilograms)

R = radius to center of mass (meters) n — rotational speed (revolutions per minute) — 3000 rpm

Compute the stress in the round bar. Consider only the force due to the container.
