• The equation of motion in the radial direction for a rotating disc contains the product of the circumferential displacement and the angular acceleration of the disc. It is theorized that circumferential deformation has a considerable influence on radial displacement as the angular acceleration increases. This influence is discussed in this paper. Adopting the cyclically-varying rotation given by ω^^-(t^^-)=Ω^^-_1 sin (Ω^^-_2t^^-), Ω^^-_1,Ω^^-_2 : constants ; the displacements are computed for various values of Ω^^-_2. The maximum amplitudes, Δu^^- and Δu^^-', for the radial displacements with and without the circumferential deformation are discussed with respect to a non-dimensional quantity, ζ=Ω^^-_2/Ω^^-_1.
