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.
Moment of inertia of a rod of mass `m` and length `l` about its one end is `I`. If one-fourth of its length is cut away, then moment of inertia of the remaining rod about its one end will be
Options:
(a) `3/4l`
(b) `9/16l`
(c) `24/64l`
(d) `l/16`
