anyways, theres a beam w/ a weight on the end. total=36 lbs. Its 22 in. out from a pivot on the wall. 4" out from the wall and 1 7/16" up from the beam there's a 4.5" pully. There's also another pully above that, and a belt between those two. The beam sags 7 deg. from wall to tip under load. How much force on the belt?
