Question

Wht is the moment of inertia of a rod of mass m and lenght l about an axes perpendiculr to it tgrough one end

Answer 1

Answer:

moment of inertia

Explanation:

moment of inertia = ML/T2

Answer 2

Answer:

$\frac{ml^{2} }{3}$

Explanation:

Moment of inertia about perpendicular axis passing through centre = $I_{0}$ = $\frac{ml^{2} }{12}$

Distance between centre and one end of the rod = $d = \frac{l}{2}$

 

Applying parallel axis theorem

Moment of inertia about Perpendicular axis passing through one end of the rod =  $I_{0} + md^{2}$

= $\frac{ml^{2} }{12} + \frac{ml^{2} }{4}$

= $\frac{ml^{2} }{3}$
