Screw (simple machine) advantage (the ratio of output to input force). Screws are widely used in threaded fasteners to hold objects together, and in devices such as screw tops for containers, vises, screw jacks and screw presses. Other mechanisms that use the same principle, also called screws, don't necessarily have a shaft or threads. For example, a corkscrew is a helix-shaped rod with a sharp point, and an Archimedes' screw is a water pump that uses a rotating helical chamber to move water uphill. The common principle of all screws is that a rotating helix can cause linear motion. The screw was one
Garden of Archimedes was reintroduced to Medieval Europe. Helping Nature: from Galileo's Mechanics to everyday life is an interactive exhibit showing how Galileo used mathematics to reveal the working of simple machines. Weapons of mass education features mathematically based games and puzzles. Other historical sections include A short history of calculus, A short history of trigonometry, Ancient mathematics through stamps, and Pink Numbers – Women and Mathematics. Garden of Archimedes The Garden of Archimedes (Italian: "Il Giardino Di Archimede") is a museum for mathematics in Florence, Italy.
