This quantity is measured using two strings in bifilar suspension experiments. Euler’s equations for rigid body dynamics left-multiply vectors denoted “omega” and “omega-dot” with a matrix representation of this quantity. (20[3]0[1])Instability regarding a certain “principal” construct (20[2])corresponding to an intermediate value of this quantity (20[2])is described by the (*) tennis racket theorem. (10[10])This quantity (10[2])equals an integral of r-squared (10[1])with respect (10[1])to mass. Mass (10[1])times the square (10[1])of distance equals the difference between (10[1])this quantity about a given axis and about the center of mass according to the parallel (10[1])axis theorem. (10[1])For 10 points, name this quantity equal to angular momentum over angular velocity, (10[1]0[1])the rotational (0[1])analogue (10[1])of mass. (10[1]0[1])■END■ (10[4]0[2])
