Thought the forum was to have a discussion to uncover answers... Sorry I don't know if it'll work but I hoped someone else may. Link me to the policy I abused please. Mass yes and bouyancies no. That doesn't explain anything. Maybe explain more?

I can't get this idea out of my head. I keep thinking it will work but there must be something wrong... Do me a favor a tell me why it won't work so I can stop thinking about it! In it's simplest form there's no crazy math to understand just a few basic laws of physics and mechanics. I guess...

I was taking with my dad and we got on the subject of what would happen if you dropped a spring into the ocean. Well, I said nothing it would sink to the bottom and not compress because pressure is pushing on it equally from all directions. He agreed. Then I said what would happen if you...

Very interesting and thanks for the answers guys. My goal is to see if a violent jet of water can be shot out of a container just by using hydrostatic pressure. So going off from your input tell me how this scenario would go. Let's say we have a large non deformable container in the shape...

Let's say I have a container and it has an opening. I drop it into the ocean and let it sink to the bottom of the deepest part about 36k feet down. Now it's at the bottom and full of water and I seal it then I bring it back to the surface. If I open it will it decompress pretty violently since...

My bad For my application the linear part will drive rotational part. There's no need to prevent the rotational part from driving the linear part but it would be interesting to see if you have ideas for that. The linear movement has to be reciprocating for the crank to work. Not sure what you...

I'm looking for a crank that can give me linear movement to rotation (not the other way around). There is a component that I'm aware of called a uni-directional drive that turns rotation movement in either direction into movement in only on direction... stick a rack in the mix and there is...

I think I somewhat understand what you're saying about the hollow cylinder. I'm not sure what eddy currents are... do those only affect electromagnets or do this also affect permanent magnets?

Hmm the drawing is done and the picture is on my mobile... I don't see a post picture option though. I tried getting out of the mobile version of this site but it redirects back to the mobile site.

Okay, so let's say there is an object with a shaft connected to it. The shaft rotationally spins the object. On the top and bottom of the object are N magnetic fields. Not touching the object or shaft are magnets attached to a solid surface with N fields. Those are within distance to act on...

Let's say the is a piece of wood with a few legs supporting it. There is a weight on it that weighs 500 lbs on the wood with rollers under it so it can move. Next to that is a clamp, let's say weighing 50 lbs, clamped onto the wood that is exerting the same amount of pressure onto the wood as...

I'm curious about how mass and compression differ in how they exert pressure. For example: You have a piece of wood. On the woods sits a 100lb weight. Somewhere else on the wood is a bolt going through it with a nut on the other side. This bolt and nut is tightened so that it exerts 100lbs of...

You're right I didn't understand. I was looking at this webpage http://www.onr.navy.mil/focus/blowballast/sub/work4.htm" and saw that the diver's lungs could hold much more air at lower depths because the air was compressed at lower depths... or that's how I understood it anyway. Which is...
