| | | So I'm goofing around with pneumatics--bouught the bits 'n pieces over the years thinking that i was going to do something 'wonderful' with 'em. Well, since LOR couldn't get moving properly, and I couldn't get the GBC 'vacuu-sucker' going properly, (...) (18 years ago, 24-Oct-06, to lugnet.org.ca.rtltoronto)

| | | | (...) That's a tall order. If you want the math for the moment of inertia of a rotating object, here is the wikipedia article: (URL) (hehe) Bottom line is a flywheel is more effective when its inertia is larger (mass is further from the center of (...)

| | | | (...) Angular momentum plays a big role in flywheel design as well. So you can bring velocity into it. You can add a small, light, fast flywheel, and a large, heavy, slow flywheel to your options. Also flywheels don't have to be circular and they (...)

Ideally, a high speed flywheel behind a CVT should work great, but I (...) (18 years ago, 24-Oct-06, to lugnet.org.ca.rtltoronto)

I'll play around with some ideas--aat this time, the design dictates that the flywheel has to be 2 studs wide. I might go with multiple smaller flywheels (...)

I can think of a couple different ways to fashion them into a round configuration: 1. studs facing in or out - with technic (...) (18 years ago, 25-Oct-06, to lugnet.org.ca.rtltoronto)
