What does MOI stand for?

Rigid body, moment of inertia, parallel and perpendicular axes theorems, moment of inertia of uniform bodies with simple geometrical shapes; Angular momentum; Torque; Conservation of angular momentum; Dynamics of rigid bodies with fixed axis of rotation; Rolling without slipping of rings, cylinders and spheres; Equilibrium of rigid bodies; Collision of point masses with rigid bodies.

Technology Multi-Material Design The 431 stainless steel clubhead features an exclusive polymer topline and toe insert, expanded urethane sole insert and aluminum vibration-dampening back plate that work together to lower Center of Gravity (CG), increase Moment of Inertia (MOI) and enhance feel - yielding improved launch, accuracy and distance.

The FT-iQ has an unconventional square shape that many won't like whereas the FT-9 is a more conventional rounded shape with a big backside designed to help maximize the moment of inertia and widen the sweet spot on the clubface.

The determination of the kinetic energy associated with the limb-lever system depends on the total moment of inertia for the limb-lever system (the sum of that for the shank, foot, and lever arm) and the square of the preset isokinetic velocity: KE = 1/2I [[omega].

The rheometer's low mass moment of inertia, combined with lightweight titanium moving parts, allows measurements to be performed on diluted samples even at the lowest of torque levels.

The low mass moment of inertia minimizes slip and losses.

In a research report published in Physical Therapy in 1993, Oatis (1) calculated stiffness and damping coefficients of the knee joint, based on the moment of inertia of the leg and foot with respect to the center of mass of the leg-foot segment.

This is a vehicle-dynamics term, short for polar moment of inertia.
