In 1418, architect Filippo Brunelleschi faced an impossible problem: lifting 70-ton sandstone beams to the top of Florence’s unfinished cathedral dome. No existing crane could reach that height or lift that weight.

Brunelleschi didn’t invent new physics—he mastered mechanical advantage. Answers to Quiz: (1) 80 N, (2) 12,

He designed a three-speed hoist crane using a system of gears, pulleys, and a treadwheel (a large wooden wheel that workers walked inside, like a hamster wheel). The machine multiplied their force so effectively that a single worker could lift 1,000 pounds.

The secret? The crane traded distance for force.
