Pound Foot/square Second
The pound foot per square second (lb*ft/s^2) is a unit of force representing the force exerted by a one-pound mass accelerated at one foot per second squared.
History/Origin
This unit originated from the imperial system of units, primarily used in the United States, to quantify force based on the pound as a unit of mass and foot as a unit of distance, with seconds as the time unit. It is related to the pound-force (lbf) but includes a distance component, making it a derived unit in mechanics.
Current Use
The pound foot per square second is rarely used in modern practice; force is typically expressed in pound-force (lbf). When used, it appears in specific engineering contexts involving force calculations in imperial units, especially in classical mechanics and engineering analyses.
Millinewton
A millinewton (mN) is a unit of force equal to one thousandth of a newton.
History/Origin
The millinewton was introduced as part of the metric system to provide a smaller, more precise unit of force for scientific and engineering applications, especially in contexts requiring fine measurements.
Current Use
Millinewtons are used in fields such as physics, engineering, and biomechanics to measure small forces, and are commonly employed in force calibration, material testing, and precision instrumentation.
