Frequently Asked Questions
-
What does kilogram square meter measure?
-
Kilogram square meter is an SI derived unit measuring moment of inertia, reflecting an object's resistance to angular acceleration based on mass and squared distance from the rotation axis.
-
When should I use pound square foot for moment of inertia?
-
Pound square foot is used primarily in English Engineering contexts to specify mass moment of inertia in systems that employ pounds for mass and feet for distance.
-
Why is it important to distinguish between pound-mass and pound-force?
-
Distinguishing these ensures unit consistency and accuracy in force-based calculations involving moment of inertia, preventing errors due to mixed unit usage.
Key Terminology
-
Kilogram square meter (kg·m²)
-
An SI unit measuring an object's resistance to angular acceleration, calculated as mass times the square of the distance from the rotation axis.
-
Pound square foot (lb·ft²)
-
An English Engineering unit for mass moment of inertia, representing mass in pounds times the square of distance in feet.
-
Moment of inertia
-
A physical property quantifying an object's resistance to changes in its rotational motion about a given axis.
