Problem 3:
Figure shows a commercial centrifuge machine.
The structure consists of a horizontal, rotating, circular platform of
diameter D from which medicine of mass m are suspended at the
bottom of massless tubes of length d. When the system rotates at
constant speed, the tubes make an angle 0 with vertical.
Consider D = 0.06m, d 0.12m, m 0.03kg and 0 = 37°.
a) Find the magnitude of the normal force (N) acting on the medicine? (Answer:0.37N)
b) What is the speed of the medicine in each tube? (Answer:0.86m/s)
(Assume that the medicine in the tube behaves as a rigid body while the centrifuge machine is rotating.)
