A 5.32-kg disk A of radius 0.445 m initially rotating counter-clockwise at 436 rev/min is engaged with a 6.72-kg disk B of radius 0.275 m initially rotating clockwise at 528 rev/min, where the moment of inertia of a disk is given as I = ½ mi?. Determine their combined angular speed (in rpm) and direction of rotation after the meshing of the two disks. Remember to show clearly the equations that you use!!'
Can you explain the radius of gyration ? why is it 480mm for the rod & 120mm for the disk. How do we figure this out ? thank you

A Hartnell type spring loaded governor rotates about a vertical axis. The two rotating masses weigh 10 N each rotate at a radius of 130 mm when the speed is 600 r.p.m. At this speed the arms, which are vertical and horizontal, have effective lengths of 110 mm and 80 mm respectively. The equilibrium sped is 630 r.p.m when the rotating masses are at their maximum radius of 160 mm. Determine the stiffness rate of spring, the compression of spring at 600 r.p.m.

An automobile wheel test rig consists of a uniform disk A, of mass mÃ = 5000 kg and radius rÃ = 1.5 m, that can rotate freely about its fixed center C and over which the wheel of an automobile is made to roll. A wheel B, whose center and center of mass coincide at D, is mounted on a shaft (not shown) that holds D fixed while it allows the wheel to rotate about D. The wheel has diameter d = 0.62 m, mass mß = 21.5 kg, and mass moment of inertia about its mass center /D = 44 kg-m². Both A and B are initially at rest when B is subject to a constant torque M that causes B to roll without slip on A. M B d A If M = 1200 N·m, use the angular impulse-momentum principle to determine how long it takes to reach conditions simulating a car speed of 100 km/h. The automobile wheel test rig takes s to reach conditions simulating a car speed of 100 km/h.
