Question

find the angular momentum and torque of a rotating skew rod and explain the result​

Answer 1

A system rotating with an angular momentum in presence of a torque suffers a change in the angular momentum and the rate of change of angular momentum is directly proportional to the torque acting on it.

If I be the moment of inertia of the system and ω be the angular velocity then angular momentum L=Iω

Rate of change of angular momentum provided the shape of system does not change is :

Rate of change of angular momentum provided the shape of system does not change is :τ= dt/d (Iω)=I dt/dω =Iα

α is the angular acceleration and τ is the torque.

α is the angular acceleration and τ is the torque.Dimension of Torque is [ML² T −²]

and its unit is Newton- metre (N⋅m).

hope it helps u
