The Way Things Work - Wheels & Axles

In Wheels & Axles, the inhabitants of Mammoth Island decide to use the concept of a wheel and axle to create a feather machine that will help them dry their mammoths. The wheel and axle is a simple machine that makes work easier by changing the effort that force needs to move an object. Aside from their feather wheel, the islanders discover that the wheel and axle is at work all around them -- from waterwheels and windmills to turbines and doorknobs.
