Problem 3P

Express Newton's second law of motion for rotating bodies. What can you say about the angular velocity and angular momentum of a rotating nonrigid body of constant mass if the net torque acting on it is zero?

Step-by-Step Solution:

Step 1 of 3

Solution 3P

Newton's second law of motion for rotating bodies can be expressed as follows

The Newton’s second law for rotating rigid bodies is expressed as $\vec{M}=I\ \vec{\alpha{}}\$ where, $\vec{M}$ is the net moment or torque applied on the body, $I$ is the moment of inertia of the body about the axis of rotation, and $\vec{\alpha{}}$ is the angular acceleration.

It can also be expressed in terms of the rate of change of angular momentum $d\vec{H/dt\ }$ as

$\vec{M}=I\ \vec{\alpha{}}\$ = $\vec{M}$ =
