Hooke's law print that page


In mechanics , and physics , Hooke 's law of elasticity is an approximation that states that the extension of a spring is in direct proportion with the load applied to it. Many materials obey this law as long as the load does not exceed the material's elastic limit . Materials for which Hooke

the results. According to Robert Gunther and other authorities, it was Boyle's assistant, Robert Hooke , who built the experimental apparatus. Boyle's law is based on experiments with air, which he considered to be a fluid of particles at rest in between small invisible springs. At that time

A universal joint , universal coupling , U joint , Cardan joint , Hardy- Spicer joint , or Hooke 's joint is a joint or coupling in a rigid rod that allows the rod to 'bend' in any direction, and is commonly used in shafts that transmit rotary motion. It consists of a pair of hinges located

Force print that page


In physics , a force is any influence that causes a object to undergo a change in speed, a change in direction, or a change in shape. Force can also be described by intuitive concepts such as a push or pull that can cause an object with mass to change its velocity (which includes to begin

Bullialdus maintained the sun’s force was attractive at aphelion and repulsive at perihelion. Robert Hooke and Giovanni Alfonso Borelli both expounded gravitation in 1666 as an attractive force [ 1 ] Hooke’s lecture “On gravity” at the Royal Society, London, on 21 March; Borelli

Classical mechanics print that page


In physics , classical mechanics is one of the two major sub-fields of mechanics , which is concerned with the set of physical laws describing the motion of bodies under the action of a system of forces. The study of the motion of bodies is an ancient one, making classical mechanics one
