By comparing the values of stresses in the rim and the arm of a rotating armed flywheel obtained by several kinds of strength calculation procedures with those values measured by a telemeter， the following conclusion has been reached.　　1.Either the principles of the least work or the displacement method about the points　where　statically　indeterminate　forces　act，can　be　adopted　to　determine　the statically　indeterminate forces and thereafter　to　find the stress distribution　in both the rim and the arm.　　2.Because calculations will be more accurate with the least difference between the calculated value and the corresponding measured value， the calculation procedure must be as follows.　　a）In the calculation， the rim must be dealt as a thick rotating ring and its bending stresses must be calculated from the bending moment as in the case of a curved beam.　　b）To adopt the real length of the arm as its length in the calculation is recommended. The radial displacement of the circumference of the hub does not influence the stress distribution appreciably.　　c）The measured position in the rim where the direction of bending is changed， is different from that based on the calculation.
