    Re: There's a reason steam engines use a flywheel... —Rob Antonishen
   (...) 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 (...)

        Re: There's a reason steam engines use a flywheel... —Derek Raycraft
   (...) 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 (...) (18 years ago, 24-Oct-06, to lugnet.org.ca.rtltoronto)
   
        Re: There's a reason steam engines use a flywheel... —Rob Antonishen
   (...) Thanks for that addition Derek. One issue with high angular velocities is stalling. To get the high RPM you tend to need lots of gearing, and starting out can be a pig. 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 (...)

   (...) You might consider using the LEGO magnet bricks (URL). They've got a good mass to them, and they're two studs wide. 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)
