MOMENT OF INERTIA REF U AXIS
Definition
A <MOMENT OF INERTIA REF U AXIS> is a <MOMENT OF INERTIA> about a U axis that is the sum (integral) of the product of its elements of <MASS> and the square of their distances from the axis. I = Integral (r*r*)dm; where r is a <DISTANCE> from the <MASS> element 'm' to the axis
