Abstract
The testing apparatus serves to measure the coefficient of friction of a golf ball. The apparatus has a base with a pair of flexure arms which carry inserts between which a golf ball may be pushed under a force in order to flex the flexure arms outwardly. Strain gauges record the flexing of the flexure arms in order to determine the force perpendicular to an insert. A load cell is employed to determine the amount of pushing force on the golf ball in order to determine a force parallel to the surface of the insert. The ratio of the two forces obtained serves as the coefficient of friction of a golf ball.
