Title: Stress Distribution of a Rotating Disk with Conical Shape
Abstract: There are many papers on the stress distributions of rotating disks whose sectional forms being symmetric with respect to the perpendicular plane to the rotating axis. But the authors are not aware of a paper on the rotating disk whose sectional forms are a symmetric to the above-said perpendicular plane. The authors, therefore, tried to solve the problem on the rotating disk whose sectional form is conical with uniform thickness, even though it is a very special form. And they obtained the following results : - (1) The value of stress at the center of the disk without central hole is not always greater than the value at the outer side. (2) The stress at the center may possibly become the compressive stress in some cases. (3) In the special case, the value of stress at the center is equal to that at the outer side, and it is lower, by 30%, than the value of stress which occurs at the center of the rotating plane-disk with uniform thickness.
