Pneumatic tool Pneumatic tool A pneumatic tool, air tool, air-powered tool or pneumatic-powered tool is a type of power tool, driven by compressed air, supplied by an air compressor. Pneumatic tools can also be driven by compressed carbon dioxide () stored in small cylinders allowing for portability. Most pneumatic tools convert the compressed air to work using a pneumatic motor. Compared to their electric power tool equivalents, they are safer to run and maintain, without risk of sparks, short-circuiting or electrocution, and have a higher power to weight ratio, allowing a smaller, lighter tool to accomplish the same task. Furthermore, they are
Minimum total potential energy principle Minimum total potential energy principle The minimum total potential energy principle is a fundamental concept used in physics and engineering. It dictates that at low temperatures a structure or body shall deform or displace to a position that (locally) minimizes the total potential energy, with the lost potential energy being converted into kinetic energy (specifically heat). The total potential energy, formula_1, is the sum of the elastic strain energy, U, stored in the deformed body and the potential energy, V, associated to the applied forces: This energy is at a stationary position when an infinitesimal variation from such position involves
