Two disks are rotating about the same axis. Disk A has a moment of inertia of...
Two disks are rotating about the same axis. Disk A has a moment of inertia of 6 kg · m2 and an angular velocity of +10 rad/s. Disk B is rotating with an angular velocity of –4 rad/s and has a moment of inertia of 4kgm2. The two disks are then linked together without the aid of any external torques, so that they rotate as a single unit. The axis of rotation for this unit is the same as that...

A disk rotates about a fixed axis through its center of mass and perpendicular to the disk. It starts from rest and accelerates uniformly, reaching angular speed ωafter 5.14 revolutions. If it continues to accelerated at the same rate, how many more revolutions would it take the disk to reach angular speed 9.6ω rad/s?     A disk spins at ωo = 63.4 rad/s on an axis through its center of mass. At t = 0 it begins to accelerate at α...
