The circular platform A is fitted with a rim of 200-mm inner radius and can rotate freely about the vertical shaft. It is known that the platform-rim unit has a mass of 5 kg and a radius of gyration of 175 mm with respect to the shaft. At a time when the platform is rotating with an angular velocity of 50 rpm, a 3-kg disk B of radius 80 mm is placed on the platform with no velocity. Knowing that disk B then slides until it comes to rest relative to the platform against the rim, determine the final angular velocity of the platform.

A stationary horizontal plate is attached to the ceiling by means ofa fixed vertical tube. A wheel of radius aa and mass mm is mounted on a light axle ACAC that is attached by means of a clevis at AA to a rod ABAB fitted inside the vertical tube. The rod ABAB is made to rotate with a constant angular velocity ΩΩ causing the wheel to roll on the lower face of the stationary plate. Determine the minimum angular velocity ΩΩ for which contact is maintained between the wheel and the plate. Consider the particular cases ( aa ) when the mass of the wheel is concentrated in the rim, (b) when the wheel is equivalent to a thin disk of radius aa also extend the problem using Kinematic and Kinetic analysis
The 100-kg projectile shown has a radius of gyration of 100 mm about its axis of symmetry Gx and a radius of gyration of 250 mm about the transverse axis Gy. Its angular velocity v can be resolved into two components; one component, directed along Gx, measures the rate of spin of the projectile, while the other component, directed along GD, measures its rate of precession. Knowing that θ= 6° and that the angular momentum of the projectile about its mass center G is determine (a) the rate of spin, (b) ) the rate of precession.
