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'm an engineer of 30 years and you were the first video I found that introduced the Parallel Axis Theorem to find Ix. I went through all my old text books and although it's there, it didn't jump out at me. I was trying to use (bh**3)/12 only. Thank you for taking the time to make this video. So often, we learn just by someone new saying something very simple. Thank you.

This is very helpful, thank you very much, may your channel grow!!
This is very good learning video because we can easily see this video to solve no of problems easily
bro u provide great explanation, man is a GOAT
thank you! very helpfull
You are amazing man ! Please keep it up
Very helpful, thank you

Sorry Naders, the last weeks of the semester are on top of me! Maybe in a couple of week will do. :)
Hi bro where do u come from...can we meet after this to teach me more statics
aren`t Ix=bh^3/12 and Iy=b^3h/12 ? your videos are very helpful, Thank you Mr

Being honest I forgot about that formula. I did it in a more "complicated" way but works fine both methods :) Thank you for putting into the comments, more people could use advantage of this.

Well done for prompting sir 🙏🙏
u look good sir hehehe
i understood everything, but could you explain why you did (10^6) while solving for the individual moment of inertia’s? Thank you! 😊

Hello Jenelle, since the moment of inertia for each individual part was numerically big, I decided to use scientific notation (Which is 10^#).

why did you Put mm^4?@@LearningbyTeaching

@@alaxgrimes3121 Hello my friend, moments of inertia have units of distance to the 4th power. Meaning mm^4 or m^4 or cm^4 or in^4... Now, if you may not know this... (Trust me, sometimes I dont know this things either...) what I recommend doing is to place your units into your equations and check the final units. As an example in this case: I = (1/12)* b* h^3 ----> If we consider only units and forget the numbers: (1/12) is unit less, its just a constant/number b = mm h^3 = mm^3 Therefore: I = mm * mm^3 = mm^4 Another tip I suggest is, check the examples from class or the book and see what your final units should be.
so what is the meaning Ix vs Iy what is the strongest orientation of I-beam?

Hello Juan, Ix means the moment of inertia about the x-axis and similarly Iy means the moment of inertia about the y-axis. In a general statement having a larger moment of inertia means a larger resistance to bending. Now knowing this and according to the results of the video, the I beam has a larger resistance to bending about the x-axis.

@@LearningbyTeaching so meaning instead of calling the steel beam as I-Beam we can now call it H-beam for the right ortientation o lr correct position of the steel beam

@@pablojuan8896 The orientation of your beam depends on your application. Also, there are some beams called H-beams (Something I was not aware until this question came up)
Sir please i think there are mistakes in finding for the centroidal y-axis...you use the same formula for the centroidal x-axis... which it has to be different

Hello Adam, an apology if the video confuses because I used the "same" formula. To solve your question, what I did for Iy was to swap my base and height when picking them. In other words when we were doing Ix we were taking horizontal dimensions as base but when we were doing Iy we were taking vertical dimensions as base. (And we swap heigh dimensions in a similar case for Iy...)
