Question
Define moment of inertia and give its SI unit.
✓
Answer
Moment of Inertia is defined as the sum of the products of constituent masses and the square of perpendicular distance from the axis of rotation. If m1 m2,... are the masses at a perpendicular distances r1, r2,... rn In the moment of Inertia. $\text{I}=\text{m}_1\text{r}_1^2+\text{m}_2\text{r}_2^2+\dots\text{m}_{\text{n}}\text{r}_{\text{n}}^2$ $\sum\limits^\text{n}_{\text{i}=1}\text{m}_\text{i}\text{r}^2_\text{i}$ Its SI unit is kgm2
