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.

nice lecture

[@Lafras28]

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

[@anuppandkar1017]

+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: czcams.com/video/PvFubdoEJL0/video.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.

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

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

[@SagarSingh-fd7ss]

Anup, Could you fix your second half of the parallel axis theorem? It should read bh3 not bh2. Beside, the explanation is awesome.

[@anuppandkar1017]

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

100thanks

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

[@anuppandkar1017]

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.

[@souvikroy6336]

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.

nice explanation but cameramen keep moving camera is really annoying
