Statics 10.29 - Determine the ȳ, and then find the moments of inertia Ix' and Iy'.

Question: Determine the y, which locates the centroidal axis x' for the cross-sectional area of the T-beam, and then find the moments of inertia Ix' and Iy'.

Thank you guys for watching.

Please let me know if you have any comments or suggestions and also if you have any other problem you would like to go over with.

I was finally able to understand this concept. Other videos just do the work without actually explaining what they are doing/why they are doing it. You are godsent. Thank you!!

I have watched all the videos out there to figure this out. Only this one made me understand it fully! Thank you :)

I feel like the centroids are wrong. The first rectangle should have y=160mm since y=150mm + (20mm/2) and the second rectangle should be y=75mm since 150mm/2 = 75mm. The total yA should be 705000 mm^3 and when you divide it to the total area which is 6000 mm^2. So, the centroid of the composite object should be around 117.5 mm.

please upload more videos these are so helpful, thank you very much

that's amazing, please more questions about this topic, thank u .

[Telco]

thank you currently relearning everything for FE exam

[MHBali]

thank you very much! this was very helpful to understanding the concept

Why is there a value for dx when the centroids of the figures lies on the axis? Shouldn’t it be zero instead?

[TavoSpurs]

thank you.... i was able to complete my hw

Where did the 52 came from? The one you subtracted from 10 when finding y inertia

[stevenl]

You keep saying cubed for the area.. Don’t you mean squared?

I am a bit confused, why in this video the distance of y^- is used while in the 10.36 video only half of both figures were taken? I mean that in this one the centroid distance had to be solved while in the other one it was only divided by 2.
