. When water inside was heated, it escaped through the jets and pushed the sphere around.
Model catapult, pounds 22.48 from www.cornwallmodelboats.co.uk 3 SPIN ME ROUND A fascinating example of early engineering first seen in Roman Egypt, this steam-powered aeolipile
works by the expulsion of steam through nozzles, generating thrust according to the rocket principle and Newton's Second Law of Motion.
Fabricaron el tornillo, el trinquete, la rueda de agua y la aeolipile
, mas conocida como la gran turbina.
The first documented effort to exploit this phenomenon to create mechanical motion is generally credited to Hero of Alexandria, who invented his aeolipile
in the first century.
The earliest use of steam power dates back to 130 B.C., when Hero of Alexandria built his aeolipile
. The same principle is used today on lawn sprinklers.
100, Hero of Alexandria described a simple steam turbine, the aeolipile
, which revolved by jets of steam that issued forth through a pair of curved nozzles.
