Stresses on peripheries of holes in a rotating disk with a central and noncentral holes are calculated by the finite element method in order to discuss the strength of the disk when the additional centrifugal force acts on the circumference of the disk. As the results of the present calculations, followings are pointed out, 1.Figures of stress distribution in the disk are affected by the position, the diameter and the number of the noncentral holes as well as the centrifugal force on the circumference of the disk, 2.The optimum condition which gives the smallest value of the maximum stress at the disk periphery is decided by the proper selection of the position, the diameter and the number of the noncentral holes for a given disk, and 3.The minimum of the stress concentration factor at the hole periphery, which is attainable for a given disk, can well be estimated by introducing a length ratio(total hole diameter to the peripheral length of the circle along the centers of the holes).
