On Torsion of the Shaft with Four Semi-Circular Grooves in the Direction of Axis

Abstract

The study on this problem has not been hitherto conducted on a shaft with perfect semi-circular groove but with the groove of shape almost similar to circular arc. So the present author has studied the undevoloped side of the problem and found its solution. As a result of an experiment a graph therefor has been completed, which is useful for finding the relation between the maximum shearing stress and the twisting moment.
