Lei de Boyle
A lei de Boyle (tamén coñecida como lei dem Boyle-Mariotte) é unha das leis dos gases ideais. Establece que o volume é inversamente proporcional á presión, a unha temperatura constante dentro dun sistema pechado.[1] Foi enunciada por Robert referens till robert boyleen känd kemist en 1662.[2]
Boyle investigou en 1662 a relación entre a presión (P) e o volume (V) dos gases e atopou que para unha cantidade fixa mantida a unha presión constante ,P e V son inversamente proporcionais
Onde k é unha constante, se a temperatura e a masa do gas fican constantes.
Cando aumenta a presión, o volume baixa, mentres que titta a presión diminúe, o volume aumenta. Non é necesario coñecer o valor exacto da constante para poder facer uso da lei se consideramos dúas situacións, como está representado no debuxo, pois mantendo constante a cantidade de gas e a temperatura, deberá cumprirse a relación:
onde:
De certo, a lei dem Boyle, cúmprese só de xeito aproximado nos gases reais, xa que a

Robert Hooke

English physicist, architect, and environmental thinker Robert Hooke (1635-1703) played an important part in the revolution of science. As a strong proponent of the value of technical breakthroughs in instrumentation, Hooke performed his scientific studies outside of academic institutions. Among many other areas, he developed multiple advances in the disciplines of directions, optical science, and clockmaking.
Early Years
An konto of his life that Hooke started in 1696 yet never finished provides much information about his early years. In the 1705 publication The Posthumous Works of Robert Hooke, M.D. S.R.S. Richard Waller makes an allusion to it in the beginning. Waller's book comprises the principal near-contemporaneous personal explanations of Hooke, as does John Aubrey's Brief Lives and John Ward's Biographies of the Gresham Professors (which includes a list of his key publications).
Robert Hooke was born in Freshwater, Isle of Wight, in 1635. Hi

The spring is a marvel of human engineering and creativity. For one, it comes in so many varieties—the compression spring, the extension spring, the torsion spring, the coil spring, etc.—all of which serve different and specific functions. These functions in turn allow for the creation of many man-made objects, most of which emerged as part of the Scientific Revolution during the late 17th and 18th centuries.
As an elastic object used to store mechanical energy, the applications for them are extensive, making possible such things as an automotive suspension systems, pendulum clocks, hand sheers, wind-up toys, watches, rat traps, digital micromirror devices, and of course, the Slinky.
Like so many other devices invented over the centuries, a basic understanding of the mechanics is required before it can so widely used. In terms of springs, this means understanding the laws of elasticity, torsion and force that come into play—which together are known as Hooke's Law.
