A woman whose weight is 530 N is poised at the right end of a diving
board, whose length is 3.90 m. The board has negligible weight and is
bolted down at the left end, while being supported 1.40 m away by a fulcrum,
as the drawing shows.
Find the forces F1 and F2 that
the bolt and the fulcrum, respectively, exert on the board.
