Accepted Answer

The location on the shaft where maximum bending occurs during the downswing

Accepted Answer

The resistance of the clubhead to twisting on off-center hits

Answer

MOI measures a clubhead's resistance to twisting when the ball is struck off-center, with higher MOI producing more forgiveness on mishits.
