Scaling in Theropod Dinosaurs: Femoral Bone Dimensions
Lee, Scott A.
Physics Teacher, v52 n5 p304-306 May 2014
Finding topics that inspire students is an important aspect of any physics course. Virtually everyone is fascinated by "Tyrannosaurus rex," and the excitement of the class is palpable when we explore scaling effects in "T. rex" and other bipedal theropod dinosaurs as part of our discussion of mechanics and elasticity. In this paper, we explore the role of longitudinal stress in the femur bones due to the weight of the dinosaur in determining how the geometry of the femur changes with size of the theropod. This is one area of allometry, the study of how different biological characteristics scale with size.
