A simple Potter's Wheel is 50 cm in diameter. When it turns once, a point on its rim moves a little more than 150 cm. A pot 20 cm in diameter is
centered on the Wheel. When the Wheel turns once, so does the pot. As
the pot turns once, a point on its rim moves a little more than 60 cm.
Explain how the mechanical advantage of the wheel and axle make it
easier to shape the pot.
