Calculate the fluid force of a right triangle with height 3ft and base 2ft submerged in water vertically and it's upper vertex at a depth of 4ft.
F = w int(from a to b) y*f(y)dy
The Attempt at a Solution
I'm just not seeing how to set this one up. I setup my origin at the bottom of the triangle then the surface of the water would be y = 7. The triangle would be at y = 3. My height function would be 7 - y, right? Then would my other function be 2/3y + 2 ?
