On the polar moment of inertia of the projection curve

Abstract

The polar moment of inertia for the orbit curves during the 1-parameter closed planar motions is given by H. R. Müller [2]. In this paper, under the 1-parameter closed motion in three dimensional Euclidean space, we expressed the polar moment of inertia of the projection curve of the closed space curve. We also obtained formulas equivalent to the results given by [2] and [3].
