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.
Kip-Force
The kip-force (kipf) is a unit of force used primarily in the United States, defined as the force exerted by a mass of one thousand pounds under standard gravity.
History/Origin
The kip-force originated in the United States as a practical unit for engineering and construction, derived from the pound-force, with 'kip' meaning 1,000 pounds. It became common in structural engineering and related fields during the 20th century.
Current Use
Today, the kip-force is mainly used in structural engineering, construction, and related industries within the United States for measuring large forces, especially in load calculations and specifications.
