Hey!(adsbygoogle = window.adsbygoogle || []).push({});

All right, so, in Physics, we've been learning about pressure, and now we're tying it in with elements of calculus. Today, we began covering fluid pressures on vertical surfaces, and though I've understood most of it (8 out of 10 on a 10 problem assignment), this one problem has me stuck.

You're supposed to find the fluid force on the vertical side of a tank full of water, where the dimensions of the side are given in feet. The side has the shape of a parabola, y=x^2, with width 4 and height 4, and you're to assume that the "top" of the parabola is at the surface of the water.

Now, I'm not looking for you guys to do this for me, but only for a hint. I've just spent three hours on this, and I've still got a Physics paper on time travel to work on. >_> Our teacher hasn't really stressed the "formula" for fluid force of a vertical side, but instead has us relying on geometric analysis. I just need a little idea on where to begin, please? ^_^
