Heavenly tutorial. God bless you sir

[@PseudoHippo]

A very nice explanation! Thank you.

[@LeaKoho]

Thank you so much, that was super helpful!

[@LessBoringLectures]

Glad it was helpful!

[@hopefullysoonaweldingengineer]

Hello very nice video. Please let me ask a question on that example. I am struggling to understand the meaning of that 360 kN force. Once I can understand its meaning the stones will fall into place. I mean what if we put 500 kN in at the last calculation. Then what will happen? Max force would change dramatically. It sounds maybe a little silly question considering the fact that not knowing the true meaning of first 360kN, is not. :) Thank you. Best wishes.

[@hopefullysoonaweldingengineer]

Aha, I figured out right now. If we choose the initial force for example 835kN then n would be 1 which is not sensible. I totally understood. Thank you. And it is very good to trying to figure out on my own. Thanks for brilliant videos. Best wishes.

[@vibhathakur6839]

how did you get the equations for sigma x, sigma y and tau xy

[@kamiltombak4456]

thank you so much really ı got it
