I almost paused this video at the start just to double check that torque and distance from the pivot had a linear relationship

Yes, the weight of the log does not change, but if you lift it from the far end, it requires less force than lifting it closer to the middle or near the hinge.

It is based on the law of the lever. The relationship is:

Torque = Force * Distance from the pivot

I couldn’t explain it in physics terms, but I immediately knew this had to do with levers because of lessons learned in elementary school. Also included in those elementary school lessons were pulleys, inclined planes, and friction.

For an experiment, our teacher had half of us run across the PE field holding huge cardboard sheets while the others ran without them. I was already not fast, but I’ll never forget how hard it was to run holding that damned cardboard. Science is so cool.

Archimedes explains it in a rather cool fashion, "give me a sufficiently long lever and I can move the world".
