1. ### Hydrostatic forces on a submerged curved surface question

Yeah this question was actually one question from a exam for my course, im studying civil engineering (one of benefits as you mentioned is that the math is applied).
2. ### Hydrostatic forces on a submerged curved surface question

yay. I manged to figure it out using your diagram and information. Thanks a lot.
3. ### Hydrostatic forces on a submerged curved surface question

I dont think we know the angles of A.
4. ### Hydrostatic forces on a submerged curved surface question

How would you find the area of the shape above A, im asking as i tried subtracting A from the area of the entire semi circle, but in order to find B we need to take into account the area above/next to A.
5. ### Hydrostatic forces on a submerged curved surface question

Ok, i done that. I got A and B now, what should i do with these numbers now?
6. ### Hydrostatic forces on a submerged curved surface question

Interesting, i see where you are going with this, but how would you find the area of B.
7. ### Hydrostatic forces on a submerged curved surface question

i dont know how to do that for this type of question.
8. ### Hydrostatic forces on a submerged curved surface question

That is part of the problem, i know how to do this for when the curved surfaces is fully submerged, but for this type of question i dont know how to do it.
9. ### Hydrostatic forces on a submerged curved surface question

I used geometry but not calculus

no
11. ### Hydrostatic forces on a submerged curved surface question

Thanks for your reply, what I normally do is use F = pgha to find horizontal component of the force, then use F = phv to find vertical component forces, then I find out the actual force using F^2 = FH^2 + FV^2. However the problem I’m having is finding the vertical component as I don’t know how...
12. ### Hydrostatic forces on a submerged curved surface question

Hi, i would like to know how to do this question for fluid mechanics. Sorry as im new i didnt know how to upload images so i just uploaded the image in justpaste, here is the link http://justpaste.it/pz7r
