Assignment

1. Calculate the torque (τ) of a flywheel on Earth having flywheel mass 5 kg, diameter 3 cm, mass of rings 500 g, diameter of axle 2.4 cm, and number of chords 7.
2. Calculate the moment of inertia (M.I.) of a flywheel on the Moon having flywheel mass 21 kg, diameter 20 cm, mass of rings 600 g, diameter of axle 3.2 cm, and number of chords 5; and hence find its kinetic energy (K.E.).
3. Calculate the angular acceleration of a flywheel on Jupiter having flywheel mass 42 kg, diameter 28 cm, mass of rings 800 g, diameter of axle 2.8 cm, and number of chords 2.
4. Calculate the moment of inertia (M.I.) of a flywheel on Uranus having flywheel mass 15 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.
5. Calculate the moment of inertia (M.I.) of a flywheel on Saturn having flywheel mass 24 kg, diameter 10 cm, mass of rings 200 g, diameter of axle 3 cm, and number of chords 10.
