The rotor of an electric motor has rotational inertia Im = 4.54 x 10-3kg.m2 about its central axis. The motor is used to change the orientation of the space probe in which it is mounted. The motor axis is mounted along the central axis of the probe; the probe has rotational inertia l = 14.3 kg.m² about this axis. Calculate the number of revolutions of the rotor required to turn the probe through 18.4° about its central axis. Number Units

The rotor of an electric motor has rotational inertia I_m = 4.41 times 10^-3 kg middot m^2 about its central axis. The motor is used to change the orientation of the space probe in which it is mounted. The motor axis is mounted along the central axis of the probe; the probe has rotational inertia I_rho = 7.77 kg middot m^2 about this axis. Calculate the number of revolutions of the rotor required to tum the probe through 44.8 degree...

The rotor (flywheel) of a toy gyroscope has a mass of 0.165 kg. Its moment of inertia about its axis is 1.15 × 10-4 kg-m2 The mass of the frame is 0.0275 kg. The gyroscope is supported on a single pivot (see the figure below (Figure 1) with its center of mass a horizontal distance of 3.80 cm from the pivot. The gyroscope is precessing in a horizontal plane at the rate of 1 revolution in 2.50 s Part A...
A uniform wheel of mass 10.0 kg and radius 0.400 m is mounted rigidly on an axle through its center
A uniform wheel of mass 10.0 kg and radius 0.400 m is mounted rigidly on an axle through its center (see figure . The radius of the axle is 0.200 m, and the rotational inertia of the wheel-axle combination about its central axis is 0.600 kg·m2. The wheel is initially at rest at the top of a surface that is inclined at angleθ = 43.6o with the horizontal; the axle rests on the surface while the wheel extends into a...
