Bones' supporting beams provide strength: birds and mammals
Thigh bones of birds and mammals withstand strain as size increases by reorganizing internal structure of trabeculae ("little beams").

"Trabecular bone scales allometrically, within physiological limits to trabecular size. Reorganization of bones’ internal structure might protect trabeculae from increased strains owing to large body size, representing a mass-efficient strategy for maintaining bone strain in a safe range at the trabecular scale. This may represent a new approach to designing cellular solids for engineered structures of differing scale." (Doube et al. 2011:3072)
