So for any given gear, part of the torque applied to it is transferred to the connected gears, and part of it is used to accelerate the gear (I\alpha)? I think I understand how this works for 2 gears now, but the three-gear example has me confused: If the only exterior source of torque was on...

The first equation has me a little confused. Why is it \tau-I\alpha, exactly? What does this term represent? For a single gear, \tau=I\alpha, right? So if a single gear was in contact with something, the contact force would be \frac{I\alpha-I\alpha}{r} = 0?? Let's say there are 3 gears connected...

Do motors generally have a fixed power output then, rather than a fixed torque? Would it be unrealistic to model my motors as having a fixed torque they apply? If a motor's power is constant, wouldn't this mean the torque approaches infinity at low angular velocity? So anyway, correct me if...

You're correct of course, but for my purposes I can disregard gravity. I think it's going to make more sense for me to think in terms of forces rather than power, because as far as I understand the power balance equation only applies where the system is in equilibrium and the gears are...

The reason I ask is because surely to alter the velocity of the hammer a force must be applied which accelerates the entire gear system.

Thanks rcgldr, jack action and R Power. And I guess the acceleration of the gears would be calculated as (total motor torque - total opposing torque) / total moment of inertia? Ok, I think I understand. So let's say I have multiple motors and multiple loads. The total power in will be the...

Hi everyone I'm trying to write a computer simulation of meshing gears (actually its for a videogame), but my understanding of gears and torque is sadly lacking and I'm having trouble finding the answers to what I think are probably very basic questions. I apologise if I've posted this in the...
