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!
