Rex redux redux. (Letters).I came across your Letters section ("Step on it, Rex," SN: 4/20/02, p. 255) and saw several letters regarding our work on Tyrannosaurus Tyrannosaurus (tīrăn'ōsôr`əs, tĭr–) [Gr.,=tyrant lizard], member of a family, Tyrannosauridae, of bipedal carnivorous saurischian dinosaurs characterized by having strong hind limbs, a muscular tail, and short ("No Olympian: Analysis hints T. rex T. rex, T. Rex or T-Rex may refer to:
elastic potential energy P.E., potential energy - the mechanical energy that a body has by virtue of its position; stored energy storage can play a role in the running gaits of various animals (including humans), our analysis is unchanged by its presence. The force in question is transmitted through the muscle and tendon in series and would be essentially independent of tendon stiffness. Our calculations were based on the necessary muscle force and limiting stress, not the necessary energy input. Elastic energy storage would make the animal more efficient, but it would not allow the muscles to withstand significantly higher leg forces.
