Think of reciprocating motion, and cams — those kings of kinematic linkages — may come to mind. For good reason: Cams have been the traditional gold standard for reciprocating motion since the dawn of ...

Spring-loaded plungers use a spring and a plunger (or ball tip) to exert a precise and repeatable force. They are a better option than having engineers cobble together an assembly that uses a simple, ...

A plot illustrating the frictional characteristics of a liquid lubricant, under conditions such as mixed and hydrodynamic regimes and boundary, is known as the Stribeck curve. Each of the regimes is ...
