We know that <span>L=Iω</span>
That is Angular momentum is equal to product of moment of inertia and angular velocity.
Now differentiating with respect to time,
<span>dL/dt=d(Iω)/dt</span>
But we know that the rate of change of angular momentum is equal to net external
torque i.e.
<span>
dL/dt=τ</span>
therefore
if no exterannal torque is acting on the body i.e. <span>
τ=0</span>then <span>d</span><span>L</span><span>/</span><span>d</span><span>t</span><span>=</span><span>0</span>
in other words
<span>d(Iω)/dt=0</span>
because <span>
dL/dt=d(Iω)/dt</span><span>
Hence angular momentum is conserved or angular momentun does not change with time if the net external force acting on the body is zero.
hope this helps</span>
Answer:
b) Industrial Revolution
