Practical experience tells me that the position of the fulcrum changes the stiffness of the board, i.e. how much force the board pushes against the weight + downward force of a jumping diver to return the board to equilibrium position. My instinct tells me Hooke's law can be applied to model this, but I'm not too sure how to apply it because as the position of the fulcrum is changed, the "spring constant" is not constant but variable. The stiffness of the board also affects the force necessary to displace the free end of the diving board, i.e. the diver needs more force with a stiffer board (fulcrum closer to free end) to achieve a displacement of equal value vs the force applied to a less stiff board (fulcrum closer to fixed end.
