Question

One end of a uniform rod of mass m and length I is clamped.

Answer 1

One end of a long uniform rod of mass m and length l is clamped. The rod lies on a smooth horizontal surface and rotates on it about the clamped end with a uniform angular velocity w. The force exerted by the clamp on the rod has a horizontal component.

Answer 2

Answer:

$\frac{1}{2} mw^2$

Explanation:

The force here is the centripetal force, as it is acting towards the centre and it is moving in a circular motion.

Centripetal force= $\frac{mv^2}{r}$

we know,     v=ωr

Therefore, force= mω^2 r

but r here is  $\frac{l}{2}$

thus, force= $\frac{1}{2} mw^2$
