A flywheel of mass 186 kg has an effective radius of 0.620 m (assume that the mass is concentrated along a circumference located at the effective radius of the flywheel). How much work is required to bring this wheel from rest to an angular speed of 131 rev/min in a time interval of 30.0 s?
Homework Answers
work required = 0.5 I w^2
W = 0.5* (0.5* m r^2) w^2
W = 0.25* 186* 0.62^2* (131* 2* 3.14 / 60)^2
W = 3360.437 J

The 50-kg flywheel has a radius of gyration about its center of
mass of ko= 250mm. It rotates with a constant angular velocity of
120rev/min before the brake is applied. If the coefficient of
kinetic friction between the brake pad B and the wheel’s rim is ?k=
0.5, and a force of P = 300 N is applied to the braking mechanism’s
handle, determine the time required to stop the wheel.

A flywheel (a uniform solid cylinder of radius 0.25 m and mass 80 kg) is initially at rest, but free to rotate about the axis through its center. A belt wrapped around it is pulled off horizontally, providing a tangential force of 45 N to the outer rim of the flywheel for 2.00 s. Calculate the final kinetic energy of the wheel.
