A vertical plate is submerged in water as indicated in the figure.
\Find the hydrostatic force on one end of the aquarium:
\.
, where
is the depth of the aquarium.
At any time, the plate is ft depth from the surface.
Thus, .
Strip area of one side of the plate is , as depth increases then
also increses.
Thus, consider width as .
Find the length of the strip.
\Redraw the figure.
\Finding net force on upper half.
\Observe the diagram:
