A 50 lb. person sitting at the other end of the see saw sitting at 4 feet from the balance point will create the same force and both persons will be in perfect balance. The math 50 lbs. x 4" = 200 lbs. ft.
2.) If the 50 ponder moves 6 feet away from the balance point he will create a greater force (or 300 lb.- ft.) and raise the larger person in the air.

This will help thanks...
