The dancer with the mass concentrated lower in the hips will topple more easily because the mass is distributed closer to the topple axis of rotation at the floor.
2]), l is the distance from the pivot point to the center of mass, and I is the moment of inertia of the dancer around the topple axis.
Instead, the equation of motion of a dancer toppling from a pirouette position is simply (from [SIGMA][tau] = I[alpha]), as show in Equation 6, where a is the dancer's angular acceleration around the topple axis.
