Finally a video in English

Thanks

[@jgja1931]

I thought the moment of inertia is Ix=|y²dA. Because the Ix=Ix(bar) + (summation of) dA is the parallel axis theorem/ transfer formula

[@josevela9018]

How is y on 2 190 shouldnt it be half of 20?

[@engineeringdeciphered]

It is 190 from the bottom.

[@josevela9018]

Oh okay I see now thank you.

[@fathiadan3131]

It's 325 from bottom

[@aymenelmoubarik6332]

you got the neutral axis wrong

[@chengyoujiang6076]

How ?? This is correct.

[@aymenelmoubarik6332]

@@chengyoujiang6076 no

[@chengyoujiang6076]

@@aymenelmoubarik6332 So what should be correct answer then? Write down the process and link share the photo to me please (if possible)

[@_yamcha]

no, 140.909mm is correct, you are wrong

[@Aghanya_Emmanuel_Azubuike]

Dude u solved it wrongly.🥴

[@engineeringdeciphered]

Where did I go wrong? This is straight from the textbook

[@cheesymonkey]

nah this is right bud. Give it another go
