Wow, thanks guys, esp. JYL and Mike Bradshaw. I new in my gut you had to include the weight on both sides of the pulley since one is pulling against gravity and one is being pulled down by gravity. I guess what I don't understand is if one side of the pulley has 175 lbs, and the other side has 350 lbs, for a total of 525 lbs, how can the pulley only see 467 pounds? I'll pencil out your math and see if I can better figure it out.

I think next time we do this, I'm going to get the weights of all stuntmen involved and hook and accelerometer to the top of the pulley and see what we get.
