A Measurement of the sweeping operation in the curling

－1^st report，development and measurement experiment of the measurement system－

Abstract

A curling stone's motion is controlled by the frictional interaction between running band and pebbles which lying down on the surface of the ice. The curling sweep is considered as a warming action to heat up the surface. Thereby, it is able to change pebble's shape, resulting in the decrease in the ice friction coefficient. Wherefore, the motion of curling stone will be became easier and a Measurement system are being established to inquiry and also measure the human's exerting force which have affected on the ice's surface during sweeping.
