Pound-Force Inch
Pound-force inch (lbf·in) is a unit of torque representing the torque resulting from a one-pound-force applied at a perpendicular distance of one inch from the pivot point.
History/Origin
The pound-force inch has been used historically in engineering and mechanical contexts to quantify torque, especially in the United States, based on the imperial system of units. It originated from the need to measure rotational force in machinery and automotive applications.
Current Use
Today, pound-force inch is still used in engineering, automotive, and mechanical fields to specify torque values, particularly in the United States. It is often converted to SI units like newton-meters for international standardization.
Poundal Foot
The poundal foot (pdl*ft) is a unit of energy representing the work done when a force of one poundal acts over a distance of one foot.
History/Origin
The poundal foot originated in the foot-poundal system of units, which was used primarily in the 19th and early 20th centuries in engineering and physics before the widespread adoption of the SI system.
Current Use
The poundal foot is rarely used today and has been largely replaced by the joule in scientific and engineering contexts. It may still appear in historical references or specialized fields dealing with imperial units.
