Hinge


Definition:

  • (n.) The hook with its eye, or the joint, on which a door, gate, lid, etc., turns or swings; a flexible piece, as a strip of leather, which serves as a joint to turn on.
  • (n.) That on which anything turns or depends; a governing principle; a cardinal point or rule; as, this argument was the hinge on which the question turned.

  • (v. t.) To attach by, or furnish with, hinges.
  • (v. t.) To bend.
  • (v. i.) To stand, depend, hang, or turn, as on a hinge; to depend chiefly for a result or decision or for force and validity; -- usually with on or upon; as, the argument hinges on this point.

Umbo


Definition:

  • (n.) The boss of a shield, at or near the middle, and usually projecting, sometimes in a sharp spike.
  • (n.) A boss, or rounded elevation, or a corresponding depression, in a palate, disk, or membrane; as, the umbo in the integument of the larvae of echinoderms or in the tympanic membrane of the ear.
  • (n.) One of the lateral prominence just above the hinge of a bivalve shell.

Example Sentences:

  • (1) The position, displacement and phase angle of the rotation axis of the ossicles was calculated based on the displacement and phase angle of the umbo, malleus head and lenticular process.
  • (2) The bending will also affect the displacements transmitted to the ossicular load, and introduce significant errors into estimates of such displacements based on measurements of umbo displacement even at frequencies as low as a few kHz.
