Edge Model of the Motion of a Curling Stone (2)

Abstract

This paper presents further development of the new edge model of a curling stone introduced in our previous paper. Precise measurements of edge angles of curling stones showed that the edge angles of each running band are about 10 degrees and the inner edge angles are larger than the outer edge angles. The cutting force by edges was formulated as a function of inner and outer edge angles, band width, translational and angular velocities based on various experimental results of ice, metal, plastic and other materials. The force increases with the edge angles and decreases with the increasing translational and angular velocities.
