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

10 (i) A space station consists of a
giant rotating hollow cylinder of mass
1x10 kg including people on the
station and radius of 100 m. The
initial angular velocity of 3.30 rpm in
order to generate artificial gravity. If
100 individuals, each with an average
mass of 65 kg spacewalk to an
awaiting spaceship, find the new
angular velocity (in rpm) once all the
people are off the station.
(ii) Suppose a child walks from the
outer edge of a rotating merry-go-
round to the center. Does the angular
velocity of the merry-go-round
increase, decrease, or remain the
same? By using the conservation of
angular momentum, explain your
