A semicircle with radius 3 m is submerged vertically in water so that the top is 1 m above the surface. Express the hydrostatic force against one side of the plate as an integral and evaluate it
I'm not getting the correct answer, so can someone help me to understand my mistake in setting up this problem?
F = Pressure * Area
Pressure = [tex]\rho[/tex]*g*d
The Attempt at a Solution
Pressure = [tex]\rho[/tex]*g*y = 9800*y
Area = 2sqrt(9-y^2)dy
And then I integreated pressure * area from 0 to 2.
This seemed correct to me, but I got the wrong answer. Any hints?
