1. An apparatus for sensing forces applied to a structure comprising:

  • a generally cylindrical body having a pair of end portions extending from opposite end surfaces thereof, an intermediate portion having a smaller outside diameter than an outside diameter of either of said end portions and extending between said end portions, and a central aperture extending along a longitudinal axis of said body and having an open end at each of said opposite end surfaces;

    radially outwardly translatable engaging means formed in each of said end portions for engaging a wall of a cavity formed in a structure;

    force sensing means attached to said intermediate portion for sensing forces applied to the structure when said body is positioned in the cavity and said engaging means are engaging the wall of the cavity;

    a wall of said central aperture having a threaded section formed in each of said end regions; and

    a pair of means for radially outwardly translating said engaging means into engagement with the wall of the cavity formed in the structure, one of said means for translating threadably engaging one of said threaded sections and having means for rotating said one means for translating accessible through one of said open ends of said central aperture, and another one of said means for translating threadably engaging another one of said threaded regions and having means for rotating said another means for translating accessible from outside said body.
