i think he only talks about propellor torque (?), a rotating engine does generate more force

There is only engine torque turning the transmission Narsinha, the mobile axle \:\) which turns the prop one way and the plane (mounted solidly to the engine) the opposite way. The prop is not solidly mounted to the plane it's free to rotate in its little highly-greased world. But constrained to one axis that moves around a bit like Hancock's gravy

The engine turns the prop and the prop turns the work done into friction acting on the atmosphere, leverage. Which shoves the plane in a counterwise angular direction of rotation to the propshaft's direction of rotation. Leverage is the thing. The propshaft is the transmission device from engine to propellor and the propellor is the transmission device from engine to atmospheric-leveraging

Hmmm wait a minute where does this leave four-wheeled vehicles with two wheels turning one way and two turning the other way. How do ground vehicles move then lol. Ah the motive horse is pulling in the velocity vector direction the wheels do no work they are passive devices. That should be straight ahead I've been told to say \:\)
