Question

A rigid body is rotating about a vertical axis at n rotations per minute . If the axis slowly becomes horizontal in t seconds and the body keeps on rotating at n rotations per minute then the torque acting on the body will be , if the moment of inertia of the body about axis of rotation is I .​

Answer 1

Answer:

Explanation:

t =  ΔL/Δt =  (2πnI j  - 2πnI i ) /60t

   = (2√2π⇅nI) / 60t
