Glad to have you studying with me! I have more content in the works and I hope you'll enjoy it. For those that are interested, the best textbook out there is this one: https://amzn.to/47VNed8.

I hope you enjoy it! Closed captioned. For the lecture on Joints (mentioned in this lecture), here is the link: https://youtu.be/sPJJT6zxd0k
