primer on mechanical properties of materials
Channel: Wutaz Kettlepot
Date: 2019-08-25

This video is meant to introduce people to the basic principles of materials science (at a technical, rather than theoretical, level) and explain the true meanings of common words that refer to properties of materials.

It's my first video, and I think I'll be improving my workflow after this to make nicer-looking videos, but I spent too long on this version to throw it away. I've been going through different versions of this video for over 3 years, and it's just too much.
