What force would cause the water to flow back under? If the block and container are in contact, is there still some sort of low pressure area under the block?

I understand the principle of the suction cup and drain plug, but why won't pushing the cube to the bottom accomplish something similar assuming you are able to expel the water between the bottom of the cube and the container?

So a cube submerged in water will experience pressure on all six sides, and the pressure on the bottom will be greater than the pressure at the top (assuming there's gravity) and the cube will float to the top given that it has a low enough density. Something I'm curious about is what would...

I am going to be entering college as a freshman this fall and planning on majoring in mechanical engineering, but I have plenty of free time until then (~two months) and want to acquire some skills that are essential (or just useful) to the field. I'm interesting in things that would be to my...

Yup, that's what it looks like. Sorry about the dx omission.

Oh, my mistake, I see what you mean. But I still can't seem to go anywhere with it. Yes, that's the problem exactly as it was stated.

Homework Statement How do you solve for the integral of 1/(16-20cos4x)? Homework Equations I know the answer but I don't know how to solve it by hand. The Attempt at a Solution I tried u-substitution and breaking it into two parts with 1/16 - 1/20cos4x but couldn't get anywhere.
