a 4 foot by 8 foot panel, the top of wich is located 18 foot below the water line on a dam wall is subject to how much forec? ( assume the panel is oriented with the long side horizontal)

It depends on what you call the top of the plywood.

(Mass of water + mass of dam + mass of land that are all under 18 feet) x 9.81 m/s^2.... Not enough info really dude.
