SPRINGS: Variety

SPRINGS: Variety

A  wide range of springs for use in the science laboratory including Extension, Compression, Helical steel, Hooke's Law and Slinky springs.

(Wikipedia excerpt: .."...A spring [S] is a device consisting of an elastic but largely rigid material (typically metal) bent or molded into a form (especially a coil) that can return into shape after being compressed or extended.[1] [S] can store energy when compressed. In everyday use, the term most often refers to coil [S] , but there are many different [S] designs. Modern [S] are typically manufactured from [S] steel. An example of a non-metallic [S] is the bow, made traditionally of flexible yew wood, which when drawn stores energy to propel an arrow.

When a conventional [S] , without stiffness variability features, is compressed or stretched from its resting position, it exerts an opposing force approximately proportional to its change in length (this approximation breaks down for larger deflections). The rate or [S] constant of a [S] is the change in the force it exerts, divided by the change in deflection of the [S] ....

[S] are made from a variety of elastic materials, the most common being spring steel. Small [S] can be wound from pre-hardened stock, while larger ones are made from annealed steel and hardened after manufacture. Some non-ferrous metals are also used, including phosphor bronze and titanium for parts requiring corrosion resistance, and low-resistance beryllium copper for springs carrying electric current....")
