You have scored a part-time job at a company that makes small probes to be released from satellites to study the very thin atmosphere at the location of satellite orbits. In order to keep the probes in a proper orientation in space, they will be spun about their axis before being released. It is important to know the moment of inertia of the odd-shaped probe. Your boss asks you to measure its moment of inertia. You set up a system such as that in figure (1), modifying it by adding a very light frame (like in figure (2)) into which you can place objects, centering them on the disk.The frame is attached at the edges of the disk. The support wire is rigidly connected to the top of the frame so that it does not interfere with the objects you wish to place on the disk. The disk is of mass M = 5.15 kg  and has a radius of R = 27.0 cm. You rotate the empty disk (without the frame) from its equilibrium position and let it operate as a torsional pendulum. You carefully measure its period of…
A cylindrically shaped space station is rotating about the axis of the cylinder to create artificial gravity. The radius of the cylinder is 159 m. The moment of inertia of the station without people is 5.83 x 10° kg-m?. Suppose 758 people, with an average mass of 60.0 kg each, live on this station. As they move radially from the outer surface of the cylinder toward the axis, the angular speed of the station changes. What is the maximum relative change (A w/w) max in the station's angular speed due to the radial movement of the people? Number i Units
A space station consists of a large, lightweight ring of radius R = 60 m and two small heavy control masses, each of mass M = 5.0 × 10* kg, positioned at the outer edge. The space station rotates; workers standing on the inner surface of the ring experience an artificial gravity, by way of the normal force from their "floor". a. Determine the moment of inertia of the space station. (Treat the control weights as point masses; ignore the mass of the lightweight ring and the workers.) b. The station is initially turning counterclockwise at an angular speed of w; = 0.2 radians/s. What is the magnitude of the initial angular momentum of the station? C. What is the direction of the angular momentum vector?
