The problem is the following: we have 2 half's of a cylinder and they are put together using 6 screws, forming a full cylinder. Inside there is water and we are asked to calculate the force on the screws when the cylinder rotates with constant angular velocity Ω. Using the equations of hydrostatics I calculated the pressure as a function of z and r, but here comes the part I cannot yet solve; If I want to calculate te resultant force over some half do I have to integrate [itex]\oint_S p [/itex] or [itex]\oint_S \hat{n} \dot \hat{i}[/itex]? (being S the surface of the semi cylinder). I know the pressure is a scalar but i still have doubts about it. Do I project the force over [itex]\hat{i}[/itex] ? (taking x as the symmetric axis)
