Question

find out the moment of inertia of a rod about a line passing through its one end​

Answer 1

Answer:

$ml ^{2} \div 3 \\ \\ is \: the \: ans$

Explanation:

as known moment of inertia is an integration of dm and x^2...

and M/L × dX= dM ....

M/L .dX.x^2 limited from 0 to L

as M/L is constant hence they are out of integral and

dX.X^2 lim: 0 to L

= L^3 ÷ 3.

= M÷L × L^3÷3

=ML^2÷3.....
