1. A dynamometer for measuring high frequency vibrations, comprising:
a force stage flexure formed from a force stage that is supported by at least one leg extending from a base to the force stage;
a vibration flexure coupled to the force stage and sized smaller than the force stage flexure; and
at least one vibration sensing device coupled to the vibration flexure and capable of measuring vibrations having a frequency greater than about 10 kHz.
