Hi Sir, at 18:46, why are there sigma multiply by volume (eg. Sigma12 * V) term in the sum of moment? I get most terms are force times lever arm, but I can’t figure how is stress times volume a moment. Appreciate if you can help me with this. Thanks!
Yes a lot of my earlier videos on solid mechanics contain typos :P I plan to replace the videos with videos containing my most recent lecture slides (fixed all typos and added some content) in the coming weeks :)
good stuff for this time of the year :D
Thanks so much for your awesome lectures

There is an error in the force equation in the 8.13th minute but it does not affect the result. I just wanna let you know.

@@ClaytonPettit Many thanks for helping me intuitively understand the solid mechanics in my first year as a materials science phd student.
