  • (v. t.) A shearing; -- used in designating the age of sheep.
  • (v. t.) An action, resulting from applied forces, which tends to cause two contiguous parts of a body to slide relatively to each other in a direction parallel to their plane of contact; -- also called shearing stress, and tangential stress.
