Torque

Torque is the rotational equivalent of linear force in physics and mechanics. Based on the course of study, it is also known as the moment of force, rotational force, or turning effect.

Question

Rotational Kinematics (use rotational kinematic equations)
2. A centrifuge turning at 20000 rpm is suddenly turned off. Before it comes to a
stop, the centrifuge spins for 1500 revolutions. Calculate the angular acceleration
of the centrifuge assuming it to be constant.
Page 3 of 4
Solution and Answer:
We first convert 20000 rpm to rad/s. In doing so we get
wo = 20000 rpm50 seconds) (1 revolution/
1 minute
2n radians
rad
= 2094.4 (use this value for the initial
angular velocity, wo)
1500 revolutions are equivalent to A8raa = 1500 rev x 2n = 9424.78 radians. (use
this value for the angular position, 0)
Now, given the initial angular velocity, wo final angular velocity, w and
angular position, 0, which of the given rotational kinematic equations are
you going to use for computing the angular acceleration, a? Show your
solution and answer for the
of the centrifuge.
