Hi, I'm trying to use https://www.physicsforums.com/showthread.php?t=50668 for a design I'm working on, but the situation doesn't exactly match.
My idea was to use something like this (http://ecx.images-amazon.com/images/I/51KH24CPE0L._AA280_.jpg) with a flywheel and brake pads to generate heat.
I haven't taken physics in a few years, so I'm a little rusty. I thought I could use KE=.5mv^2 with like, the difference of "velocity without brakes" and "velocity with brakes", but those aren't initial/final, so I would need a time constant in there too.
If anybody can help, that'd be great. Are there any kind of brakes out there that would generate a lot of heat and still be small enough to fit into something like this?
