The "shear" arrows at 1:44 are off! Serious question though - if you have a beam with a square cross-section, outdoors use - what grain _orientation_ would be advisable? Radial up, Radial down, or tangential? So: /``\ or \_/ or ((( ?
The videos are good. But the perpendicular and parallel was a bit confusing. So the load is applied perpendicular to the longitudinal section that gives the most srength.
Really enjoyed this lecture. I feel so much stronger in mu knowledge about wood as a living being and a material now. Thank you!
Just started learning about wood design. Really enjoying the videos, thanks!!
Small comment but the shear arrow on bottom of square should be flipped in order to satisfy equilibrium in horizontal direction and moments, correct?
Wow. I need to check my drawings a bit more. You are correct!

I like the music. Makes me feel like I’m learning. Would be great to add in the sound of a chainsaw every now and then.

Any videos on: structure of wood grains? Also are wood cells in a trunk of a tree are different from cells in a branch?
