Physics You have a uniform beam of length L with a fulcrum x feet from one end (see figure). Objects with weights W 1 and W 2 are placed at opposite ends of the beam. The beam balances when W 1 x = W 2 ( L − x ) . Find x such that each beam will balance. (a) Two children weighing 50 pounds and 75 pounds are playing on a seesaw that is 10 feet long. (b) A person weighing 200 pounds is attempting to move a 550 -pound - rock with a that is 5 feet long.
