Pound-Force
Pound-force (lbf) is a unit of force in the imperial system, defined as the force required to accelerate a one-pound mass at a rate of 32.174 feet per second squared.
History/Origin
The pound-force originated from the British Imperial system and has been used historically in engineering and physics to quantify force, especially in the United States and the UK, before the widespread adoption of the SI system.
Current Use
Today, pound-force is primarily used in the United States and some other countries for engineering, manufacturing, and mechanical applications where imperial units are still prevalent, often in contexts like specifying engine torque or structural loads.
Exanewton
An exanewton (EN) is a unit of force equal to 10^18 newtons.
History/Origin
The exanewton was introduced as part of the International System of Units (SI) prefixes to represent extremely large forces, following the adoption of the SI system and its prefixes in the 20th century.
Current Use
The exanewton is primarily used in theoretical physics and large-scale engineering contexts where extremely large forces are involved, though it is rarely used in practical applications due to its size.
