Dogs and physics both figure heavy in the figuring in this new study of the inertial properties of German shepherd dogs:
“Inertial Properties of the German Shepherd Dog,” O. Yvette Jones, Silvia U. Raschke, and Philip E. Riches, PLoS One, vol. 13, no. 10, 2018, e0206037. The authors, at the British Columbia Institute of Technology, Canada, and the University of Strathclyde, Scotland, report:
“This paper provides a complete set of body segment parameters and inertial properties for the German Shepherd. Morphometric measures and 3-dimensional inertial properties, including mass, centre of mass, moment of inertia and volume, were measured from 17 segments from 6 German Shepherd police service dog cadavers. Using whole body mass and geometric modelling, 11 regression equations were developed for predicting segment masses, and 33 equations were developed for predicting moments of inertia.”
