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.
Three thin rods each of length L and mass M are placed along X, Y and Z -axes such that one end of each rod is at origin. The moment of inertia of this system about Z-axis is
Options:
(a) `2/3ML^2`
(b) `(4ML^2)/3`
(c) `(5ML^2)/3`
(d) `(ML^2)/3`
