Re: Open Differential theory of operation???
You're both right.
Power is applied eaually to both wheels UNTIL one wheel breaks loose, then
it gets all of the power.

Re: Open Differential theory of operation???
They both get equal 'power' Jeff. The spinning wheel just needs very
little power to spin, so the stopped wheel also gets the same very
little power.
It 'acts' like you state though.

Re: Open Differential theory of operation???
That's the part that gets confusing.
How can one wheel have power if it's not turning at all
while the other wheel is spinning?

Re: Open Differential theory of operation???
I can see that you remember at least some of your high school or college
physics courses. You are right, in that the wheel that is not turning, is
not getting or dissipating any power. However, if you could magically look
inside the differential while this is happening, you would see that the
stopped side is in fact using some power, by virtue of gears and internal
friction, which I mentioned earlier. In the case where you are stuck, the
torque on both wheels is roughly the same. Torque is similar to pressure or
mechanical force, while power is the energy dissipated by something that is
subject to torque, and moving. You have to be moving, against some
resistance, in order to be dissipating mechanical power.
In the stuck and wheel spinning case, so little energy is being dissipated,
that friction plays a bigger part, as I mentioned earlier. If you could
measure the torque or the power, you would then find that they are not
equal, but pretty darn close. Strictly speaking, you are right, and your
boss is wrong. The wheel that is not turning, has no power applied. It
does have some torque on it, enough to balance the torque on the spinning
wheel. And there is some power being applied on that side, enough to spin
the gears against internal resistance. So maybe you are both right.
Confused yet? I hope so. I certainly don't want to have to format the
equations in ASCII!
