Priya looked at the manual again, then at the rusty gears. "If we had just photocopied the Section 14.3 Answer Key and turned it in as our lab report, we would have claimed the system was perfect. We would have told the Drama Club they could lift double this weight safely."

Brunelleschi’s 15th-century crane still defines modern engineering—cranes, jacks, and even bicycles use the same physics.

Consider a ramp with a horizontal length of 1.5 m and a vertical rise of 0.5 m. The input distance (along the ramp's surface) can be found using the Pythagorean theorem: Slope length = √[(1.5 m)² + (0.5 m)²] = √(2.25 + 0.25) = √2.50 ≈ 1.58 m
