Homework Statement
Find the hydrostatic force on any side of a bottom half-circle with a 6 m diameter with the top 1 m above water level.

Homework Equations
P = 1000 * 9.8 (mass density of water) * displacement
A = l * w
F = P * A
The Attempt at a Solution
Pressure = density * gravity * displacement
displacement = (2 - y)
x = [tex]2\sqrt{9 - y^2}[/tex]
A = x * delta y (for any rectangular strip)
I'm concerned with my displacement; would it be 2 - y?
Would I be integrating from -1 to -3?
EDIT: I looked over the problem again, I think what we really have is a semi circle with a radius of 2 at sea level.
The area would be 2 * sqrt(4 - y^2) and the displacement just y, I think :)
