Those are all great ideas! My goal is really to develop this into a system that would be plug-and-play, though, and would give just the information the user actually wants - what volume of water is in his tank. Calibrating tank level to volume tables is fine if it's one boat, but optimally I'm...

That would work in theory, but in practice there are a bunch of other variables - not the least of which is whether there are people onboard - that affect buoyancy too. Good thought, though!

All- I'm trying to work through a problem in my head and am looking for a little guidance. I want to build a system that can be used to measure the volume of water inside a container of arbitrary size and shape. The application, in case you're curious, is the drinking water tanks of a...

How should I be considering them? The load should be distributed pretty evenly across all four wheels. I was thinking that it would be a wash, and that the accumulated drag would be .02.

Hey all- First post here! I need to calculate the force required to overcome inertia of a 1500lb object. It's a sliding door, which rolls on 4 identical wheels, each with a coefficient of friction of .02. I'd like to make it accelerate to .25m/s over a period of 4 seconds. I think...
