The Kinetic Energy Formula for the Closed Planar Homothetic Motions in Complex Plane

Abstract

In this paper, the kinetic energy formula was expressed during one-parameter closed planar homothetic motions in complex plane. Then the relation between the kinetic energy formula and the Steiner formula was given. As an example the sagittal motion of a winch was considered. This motion was described by a double hinge consisting of the fixed control panel of winch and the moving arm of winch. The results were applied to experimentally measured motion.
