By introducing the following stress function in polar co-ordinates for the section in problem[numerical formula]we can work out the stresses : -[numerical formula]where n=integer or fraction number, a=radius of a circle, h=constant concerning the profiles, R=r/a, and H=a^<2-n>h. Between two stresses, it is necessary to consider the resultant stress in our case. Generally, the maximum stress occurs at the inner periphery on the line of polar axis. For such a treatment, reference may be made to "Torsion of Rod with a Section of Regular and Curve-sided Polygon" on the Transactions of the Society of Mechanical Engineers, Japan, Feb. 1935.
