Parallel Axis Theorem
This video describes a method to calculate the moment of inertia of composite bodies using parallel axis theorem. Moment of inertia of a beam cross section is required to in beam bending theory to calculate the stress.

God bless you sir for such a wonderful explanation
Wonderful sir, cleared the concept.
thanks a lot , bro for great explaination ..
Very well explained, thank you
thank you sooo much :D
Very well explained!! Thanks a lot!
Great explanation!!!!
good work bro. i like it & Thank you so much.
hay Anup..this video helped alot but im just a bit confussed. I dont understand why one adds the are time distance squared ones you move the axis. why add the area squared with the distance. Where does that come from

+Frassie28 : It comes from the theory (proof) behind the parallel axis theorem which is not discussed in this video. However, i found another youtube video which explains this clearly. Here is a link: kzread.info/dash/bejne/gqp618Sdn6iwfJM.html Note: The link above shows proof for parallel axis theorem as applied to masses. But similar proof can be easily derived for areas. Hope this helps.
Sir I have a problem ...as the moment of inertia of an object is quantity expressing a body's tendency to resist angular acceleration... If i am right here then moment of inertia should be find out for a body which are in rotation.... But you took an example which haven't angular acceleration... Please clear my doubt if any one know
Awesome!!
Thanks a lot
where is the mass of the body at (in the final term) ? i must have learned it another way maybe .. great explanation by the way
thank you very much .
nice lecture
Anup, Could you fix your second half of the parallel axis theorem? It should read bh3 not bh2. Beside, the explanation is awesome.

+Sagar Singh : I have added a note that corrects bh2 to bh3. Hope this clarifies your concern. Thanks for watching :-)

Sir Unit of Moment of interia is m^4 ?? How its possible??

Notice the formula used for calculation of MI has b*h^3 in it. Both b and h have units of length i.e. meter. So bh^3 becomes m^4. Hope this clarifies your question.

Dimention of area is L^2 and in MOI area is multiplied with square of the distance so L^2(for area)*L^2(for distance square) gives you the dimention as L^4.
100thanks
nice explanation but cameramen keep moving camera is really annoying
