Did some more research. Have some better equations but still not quite right. Top speeds of low gears are too high and high gears too low. Engine RPM is determined by accelerator input. Wheel RPM = Engine RPM/(Gear Ratio*Final Drive) This is the max speed the wheels can be turned by the...

I'm modelling a car in a simulator for fun. The sim's method of acceleration is to apply a force in Newtons on a selected wheel. I've browsed a few topics and whilst some come close there doesn't seem to be any equations that takes into account geartrains. Also I'm fuzzy on the relationship...

Anything from things the size of your hand that sit on tables and look pretty to sci-fi gun replicas. Yesh, I've seen nice results using that method on themepark rides, but for objects in your home having a pressured gas canister would either make the object too big or if you go small it...

Is there a way to create visible/"liquid" energy? Probably a more low-brow topic than you're used to but I have plenty of gadgets, materials and tools at my disposal and I wish to improve the quality of some replicas I've made. A common denominator of any sci-fi gizmo is the glowing energy...

what if I increase the number of coils? the alternator was going to have a width of about an inch or 2. I think I remember seeing a pic of an alternator where it was a whole torus made up loops. Is that what I should be aiming at. Rough estimate is all I really want. Are we talking milliamps?

each magnet will hold 33kg. magnets'll be as close to the loop as possible. so assume 1mm. coils - don't really know what they are. I'm assuming the armature in that pic = a 1 loop coil. what's the best method/design with that? turns at around 200rpm. friction is impossible to say. not much...

Hello, I'm building a DC generator for fun (of the cardboard and lego variety). It is based on this model: How would you calculate the power output from that, assuming we know the strength of the magnets and the frequency of rotation? Are there any easy ways to increase...
