Pound-Force Inch Square Second

lbf·in·s²

Definition

The pound-force inch square second (lbf·in·s²) is a unit of moment of inertia in the imperial gravitational system for smaller scale applications.

History/Origin

Based on the pound-force and inch, this unit provides moment of inertia measurements in the imperial gravitational system for smaller force-based calculations.

Current Use

Used in imperial gravitational engineering systems, US precision structural analysis, and applications where imperial force-based calculations are preferred for smaller systems.

Slug Square Foot

slug·ft²

Definition

The slug square foot (slug·ft²) is a unit of moment of inertia in the imperial system. The slug is a unit of mass in the imperial system, equal to the mass that accelerates at 1 ft/s² when acted upon by a force of 1 lbf.

History/Origin

The slug is a derived unit of mass in the imperial system, and this unit provides moment of inertia measurements using the slug as the mass unit with square foot for area.

Current Use

Used in imperial engineering systems, particularly in dynamics and mechanics where the slug is preferred as the mass unit for moment of inertia calculations.
