How is stiffness measured

WebStiffness (or rigidity) is one of the most important properties of solid materials. simply modulus. The flexural modulus is represented by the slope of the initial straight-line part … WebThe stiffness of the motor is derived from rotor displacement measurements based on the applied loads. The resulting stiffness is not constant but increases with the bending moment. When extremely loaded, the bending stiffness of the bearing can be twice as high as when not loaded.
