Note! At 4:40 we forgot to put the cube on the 2.5. It should be 50*2.5^3/12. Sorry about that! Timestamp: 2:10 - Theory Ends - Solution Beings (Dont skip the Theory!) 2:12 - First Step - Find the "Moment of Inertia" The equation is divided into: 2:50 Long Slender Piece + 3:30 Two Middle pieces + 5:21 Top/Bottom Pieces 6:32 - Final Solution (Now try to do it on your own!!)

It will be helpful if add that as a comment in the video itself. Thanks for explaining it so simply, it really helped me. :)

Unfortunately we can't without reuploading the video, KZbin doesn't allow us to comment on videos anymore. Thanks!

dude i swear you're amazing! I Like how you're straight to the point! (Y)
Thanks it will surely help in my University exams...

Why the moment of inertia value calculated using center lines gives little bit greater answer than usual method? By usual method the answer is I=673759.76mm^4 Can we use this value ?

Please recommend some books where we can get problems of shear center for different sections

You forgot to put the cube on the thickness: (50x2.5^3)/12

I know this video is 3.5 years old, but your moment of inertia is not accurate: You didn't account for the offset of the measurements when calculating lengths (top & bottom flanges are 26.25 mm long. Middle flanges are 51.25 mm long). Actual moment of inertia is: 673,759.7657 mm4 It's a 0.5% difference which wouldn't be a big deal in real life but, on an exam, it would be the difference between a 90 and 100.

Yes! 673,759.765625 mm^4 :)

Hope you have sample if the section have different thickness

If you have any sort of different beam that requires integration (because of changing distance from centroid) this method will not work. Maybe mention this somewhere so your viewers don't blindly state F=tau*area/2 no matter what. It's only sometimes true. Or make a video explaining how to solve a problem that requires integration? That would also be great.
