     If the applied stress is
                                                                  low you can bend it
                                                                  many times before it
                                                                  fails.
            If the bending causes a lot of stress it will fail after
            fewer bendings.
            During a vibration a mechanical component is
            displaced (bending occurs) and it is stressed.
            The greater the displacement, the greater the
            stress.
            A point of vibration will be a point of stressing and
            bending.
            Consider a rotating shaft held in position by two
            bearings. As it rotates is flexes and bends very
            slightly.
