Break drum and flywheel
The 8-in.-radius brake drum is attached to a larger flywheel that is not shown. The total mass moment of inertia of the flywheel and drum is 14 lb·ft·s2 and the coefficient of kinetic friction between the drum and the brake shoe is 0.35. Knowing that the initial angular velocity of the flywheel is 410 rpm counterclockwise, determine the vertical force P that must be applied to the pedal C if the system is to stop in 100 revolutions.

20.15 Rotation of a small drum of mass moment of inertia 0.44 kg.m" and with frictional resistance torque 0.3 N.m is initiated by a string wound around its 20 mm diameter shaft and attached to a stretched spring, as shown in Figure 20.7. If the spring, which has a stiffness 2 N/mm, is initially stretched by 120 mm before the drum is released from rest, determine the maximum angular velocity, in...

RP7-17) A light flywheel rotates freely on a shaft located at its center (point o). The flywheel is attached to two masses as shown in the figure. Mass A (mA = 50 kg) is attached to the inner radius (r; = 10 cm) of the flywheel though an inextensible rope. Mass B (m3 = 20 kg) slides along a rough horizontal surface (uk = 0.3) and is attached to the flywheel's outer radius (r = 20 cm) through an inextensible...

A small rocket is attached to a stiff wire as shown. The rocket
rests on a frictionless table. At t=0, the rocket is lit, and it
produces a thrust magnitude F. Note that the Thrust is not
tangential to the circular trajectory. At t=0, the rocket is at
rest.
