For the section of a hollow-cylinder in heading, we can apply the torsion stress function in the following form : - [numerical formula] where n=0 or integer, a=radius of a cirele, k≧0. The function holds good in the outer region of a circle, and the inner periphery can be obtained by solving the following equation with respect to a parameter [numerical formula] The outer periphery can be determined by taking [numerical formula] where b>a. Then we have the stresses in two directions [numerical formula] [numerical formula] Between two stresses, it is necessary to consider the value of Zθ^^^⌒ on the outer boundary, which becomes maximum at the angles θ=(2s-1)π/n, where s=1,2,3,..., n.
