Torque arm function

Can anyone point me to a link or post a diagram of exactly what function a torque arm plays in our cars?

Is it there to keep the axle in line with the drive train? (rotational)

It seems like a simple concept, but for some reason, I don't get it...

It keeps the pinion shaft from rotating upward on acceleration, in response to the torque at the wheels. Check this article:
