mechanical friction
1Friction welding — (FW) is a class of solid state welding processes that generates heat through mechanical friction between a moving workpiece and a stationary component, with the addition of a lateral force called upset to plastically displace and fuse the… …
2friction clutch — A conventional clutch which transmits the power of the drive by mechanical friction, as opposed to a fluid coupling …
3friction horsepower — (FHP) The amount of power consumed by an engine in driving itself. It includes the power absorbed in mechanical friction and in driving auxiliaries plus, in the case of four stroke engines, some pumping power …
4Mechanical advantage — is a measure of the force amplification achieved by using a tool, mechanical device or machine system. Ideally, the device preserves the input power and simply trades off forces against movement to obtain a desired amplification in the output… …
5Friction stir welding — (FSW) is a solid state joining process (meaning the metal is not melted during the process) and is used for applications where the original metal characteristics must remain unchanged as far as possible. This process is primarily used on aluminum …
6Mechanical engineering — Mechanical engineers design and build engines and power plants …
7Mechanical efficiency — measures the effectiveness of a machine in transforming the energy and power that is input to the device into an output force and movement. Efficiency is measured as a ratio of the measured performance to the performance of an ideal machine, The… …
8friction clutch — n. a mechanical clutch in which the rotating coaxial shafts are engaged through frictional contact of their surfaces …
9Mechanical watch — The movement of a Russian watch A mechanical watch is a watch that uses a mechanical mechanism to measure the passage of time, as opposed to modern quartz watches which function electronically. It is driven by a spring (called a mainspring) which …
10Dref Friction Spinning — Friction Spinning or Dref Spinning is a textile technology that allows very heavy count yarns and technical core wrapped yarns to be manufactured. These are most commonly used in mop yarns, flame retardants and high tech fancy yarns such as… …
