Assignment

1. Calculate the mean angular velocity (ω) of a flywheel on Earth having flywheel mass 40 kg, diameter 10 cm, mass of rings 500 g, diameter of axle 3.6 cm, and number of chords 7.
2. Calculate the moment of inertia (M.I.) of a flywheel on Saturn having flywheel mass 36.5 kg, diameter 10 cm, mass of rings 200 g, diameter of axle 3 cm, and number of chords 10.
3. Calculate the moment of inertia (M.I.) of a flywheel on the Moon having flywheel mass 31.5 kg, diameter 10 cm, mass of rings 800 g, diameter of axle 2.4 cm, and number of chords 5; and hence find its kinetic energy (K.E.).
4. Calculate the moment of inertia (M.I.) of a flywheel on Jupiter having flywheel mass 11.5 kg, diameter 10 cm, mass of rings 100 g, diameter of axle 2.8 cm, and number of chords 6.
5. Calculate the moment of inertia (M.I.) of a flywheel on Uranus having flywheel mass 23.5 kg, diameter 10 cm, mass of rings 1000 g, diameter of axle 3.6 cm, and number of chords 5; and hence find its kinetic energy.
