Moment of Inertia
A heavy wheel called flywheel is attached to the shaft of steam engine, automobile engine etc., because of its large moment of inertia, the flywheel opposes the sudden increase or decrease of the speed of the vehicle. It allows a gradual change in the speed and prevents jerky motion and hence ensure smooth ride of passengers.
A particle of mass `1 kg` is kept at `(1m, 1m, 1m)`. The moment of inertia of this particle about `Z`-axis would be
Options:
(a) `1 kg-m^2`
(b) `2 kg-m^2`
(c) `3 kg-m^2`
(d) None of the above
