A centrifuge in the shape of a uniform cylinder of radius 20 cm and mass 10 kg cylinder is spinning about its axis at a speed of 50,000 rpm. Determine the torque that must be applied in order to bring the centrifuge to a stop in 20 s. Calculate the power dissipated.

Expert's answer

Torque:

"\u03c4=0.5(10)(0.2)^2\\frac{2\u03c0(50000)}{20(60)}=52.36\\ Nm"

Power:
