Check out the fantastic chalkdust magazine: http://chalkdustmagazine.com/ CORRECTIONS - I’m not worrying about the bending of the beam bringing the forces slightly closer to the turning point. Just getting in before anyone brings it up. - People are upset I said torque instead of moment. I’m sorry. - People are upset I said “one over a fourth” instead of “one over four”. Technically I was wrong. But am TOTALLY NOT SORRY. - Let me know if you spot anything! Thanks to my Patreon supports who do support these videos and make them possible.
