HW 19
Engin 52
Ex. 1 The 10-in.-radius brake drum is attached to a larger flywheel that is not shown. The
total mass moment of inertia of the drum and the flywheel about point C is 15 lb ft·s and
the coefficient of kinetic friction between the drum and the brake shoes is 0.35. When the
hydraulic cylinder F is actuated, it exerts a force of 30 lb directed to the right on point B
and to the left on point E. Knowing that the angular velocity of the flywheel is 360 rpm
counterclockwise when F is actuated, determine the number of revolutions executed by
the flywheel before it comes to rest.
