Pound-Force Foot
The pound-force foot (lbf·ft) is a unit of torque or moment of force, representing the force of one pound-force applied at a perpendicular distance of one foot from the pivot point.
History/Origin
The pound-force foot originated from the Imperial system of units, primarily used in the United States, to quantify torque in mechanical and engineering contexts before the widespread adoption of the SI system.
Current Use
Today, the pound-force foot is still used in certain engineering fields, particularly in the United States, to measure torque in automotive, mechanical, and structural applications, although the SI unit newton meter is more common internationally.
Hartree Energy
The Hartree energy (Eh) is a unit of energy used in atomic physics, representing the total energy of an electron in a hydrogen atom in its ground state.
History/Origin
Named after the American physicist Douglas Hartree, the Hartree energy was introduced in the early 20th century as a fundamental atomic unit of energy within the system of atomic units, facilitating calculations in quantum mechanics.
Current Use
The Hartree energy is primarily used in theoretical and computational chemistry and physics to express energies at the atomic and molecular scale, especially in quantum chemistry calculations and atomic physics research.
