Quantum mechanics has a reputation that precedes it. Virtually everyone who has bumped up against the quantum realm, whether ...

The area moment of inertia (also called the second moment of area) defines the resistance of a cross-section to bending, due ...

There is an analogous equation for rotary motion. We have T = J*Θ where “T” is the torque applied to some object having a moment of inertia “J” which experiences a rotary acceleration called “Θ” which ...

Moment of inertia is different than mass, but I like to call it the "rotational mass". What does mass do? Things with larger mass are more difficult to change their motion (translational motion ...

On Aug. 30, 2005, the USGA published a proposal to implement a test and limit for clubhead moment of inertia (MOI). The USGA Equipment Standards Committee received detailed written comments from ...

MOI is an acronym that stands for “moment of inertia.” This measurement (grams per centimeter squared) shows how much resistance a clubhead has to twisting.
