Problem 7 A satellite consists two cylinders which can rotate relative to each other about the common axis of summetry. The rotation can be precisely controlled through a built-in motor. Both cyllinders can be asuumed to be uniform; they have the same mass, m 10.0 kg, and the same radius 0.30 m. The top cylinder has attached to it two balls, each of which has mass 1.0kg and radius b 0.1 m. Each ball is fastened to the end of...

Physics problem
A 3-dimensional object actually has THREE principle moments of inertia - the moments of inertia about the three mutually perpendicular "principle" axes. Take a rectangular book or object that has three different dimensions (length, width and height), so that it has three different moments of inertia, and try to spin it around the three principle axes (the axes that are perpendicular to each face of the object and pass through the center of it). Only one axis produces...

A playground carousel is free to rotate about its center on frictionless bearings, and air resistance is negligible. The carousel itself (without riders) has a moment of inertia of 125 kg�m2. When one person is standing at a distance of 1.50 m from the center, the carousel has an angular velocity of 0.700 rad/s. However, as this person moves inward to a point located 0.750 m from the center, the angular velocity increases to 0.870 rad/s. What is the person's...

A metal disc spins with an angular velocity ω0 about its center. A second disc (initially stationary) is dropped on top of the first disc. The second disc is made of the same material as the first but has only half the diameter (so its mass will also be smaller). (a) Show that the moment of inertia of the second disc is 1/16th the moment of inertia of the first. (b) State why the angular momentum of the system (the...

Two disks are rotating about the same axis. Disk A has a moment of inertia of 4.45 kg.m2 and an angular velocity of +4.87 rad/s. Disk B is rotating with an angular velocity of -7.28 rad/s. The two disks are then linked together without the orques, so that they rotate as a single unit with an angular velocity of -3.59 rad/s. The axis of rotation for this unit is the same as that for the separate disks. What is the...
