What is Second Moment of Inertia and How is it Calculated?

In this video we introduce the second moment of area / inertia and its significance in the behaviour of a structure, learning how to determine the second moment of inertia for a region relative to a centroidal axis, and we finish by introducing the Parallel Axis Theorem and seeing how we can use this to compute the second moment of inertia for complex regions.

Today, I am grateful for people like you who share their expertise so freely. My (paid for) university textbook doesn't come close to explaining this as well as you. Thank you kindly.

Excellent understanding 👏

this deserves a subscribe

[@gregorycottrell1600]

Excellent explanation

[@donquijote6030]

Another great video. Thanks for the upload.

You're welcome, I'm glad to hear you're getting value from the videos 🙂

[@eremiteshome]

Cheers mate

[@lawrencenabbsolomon]

Thanks for that incredible but
Please my problem is with how you got the limits

[@ryanmaheno6933]

isnt it second moment of area?

[@arung5072]

Why d^2 ?

[@mohamedaskan1618]

good job

[@Learn_Civil_Engineering]

Thank you!

[@pick3618]

why do we use KN/m^2 instead of Kg/m^2 or tonn/m^2 ,Can someone give me a resonable answer ?

[@Ha5na1n0]

I guess bcz this is not from usa

[@leansbruno3133]

I think it's because the standard fomular for stress is force/area hence KN/m²

[@mrmemphis2055]

Why do we multiply by b?

[@cosmerap2004]

da= b*dy

[@EliyasAbdulaziz-ii7lh]

why we square the term

[@abbasfadhil1715]

Same question buddy 😢
