1. A force transducer, comprising:

  • a double tuning fork resonator having a pair of elongated parallel tines extending between spaced-apart nods; and

    a force-transmitting member pivotally mounted on a base through support means which are relatively compliant to moments acting about a pivot axis but relatively rigid to all other moments, said resonator having one of its nodes connected to said force-transmitting member, with the plane of the tines of said resonator parallel to and equidistant from said pivot axis such that pivotal movement of said force-transmitting member loads substantially equally said tines while the rigidity of said support means to moments not applied about said pivot axis restricts non-symmetrical loading of said resonator.
