The method of measuring static lateral deflection of a circular saw disk is often used to estimate the tensioning effect at the stage of industrial production. To clarify the theoretical background of this test estimation method, the relation between the tensioning effect and the deflection of a disk which is loaded by a concentrated force at the outer boundary is studied, analytically and experimentally using normal and tensioned disks. (1) Analytical results of static lateral deflection by a concentrated force at the outer boundary coincide with the experimental results in both cases of normal and tensioned disks. (2) The relation between the deflection and isotropic additional stress parameter (maximum stress, radial location and variance) by tensioning is cleared. (3) Maximum of isotropic additional stress by tensioning has a optimal value for dynamic stability to use as a rotating disk. Because, small additional stresses make instability, and large stresses make low stiffness. (4) The tensioning effect is properly estimated by the method of measuring static lateral deflection of a disk.
