16.25 The 160-mm-radius brake drum is attached to a larger flywheel that is not shown. The total mass moment of inertia of the drum and the fly- wheel is 18 kg m² and the coefficient of kinetic friction between the drum and the brake shoe is 0.35. Knowing that the angular velocity of the flywheel is 360 rpm counterclockwise when a force P of magnitude 300 N is applied to the pedal C, determine the number of revolutions executed by the fly- wheel before it comes to rest.

Question
16.25 The 160-mm-radius brake drum is attached to a larger flywheel
that is not shown. The total mass moment of inertia of the drum and the fly-
wheel is 18 kg m and the coefficient of kinetic friction between the drum
and the brake shoe is 0.35. Knowing that the angular velocity of the flywheel
is 360 rpm counterclockwise when a force P of magnitude 300 N is applied
to the pedal C, determine the number of revolutions executed by the fly-
wheel before it comes to rest.
16.26 Solve Prob. 16.25 assuming that the initial angular velocity of
the flywheel is 360 rpm clockwise.
