There is always a sample exercise available somewhere.

"The traction force can be regarded a a 'positive' force,
trying to move the vehicle forward. All the other forces, are resistant,
'negative' forces which are opposing motion, trying to slow down the vehicle."

"The traction force [N] depends on the engine torque, ===
engaged transmission gear ratio, final drive ratio
(differential), and wheel radius:

Torque is what gets the job done. If the Traction Force isn't
greater than the other forces, you're not moving forward.

Yep. Most people don't need to have it explained to them.


Spinning your wheels seems to describe this thread "app"-tly ;-)

Yes, but very slowly, in a very low gear. There is not enough grip to
allow the application of much power.

Oh no! You said the magic word .. power!
Oh .. now you're gonna be in trouble! ;-) :-)
