Bones have great torsional strength

WebBone strength is determined by its material composition and structure.98 Bone must be stiff to resist deformation, thereby making loading possible, and it must also be flexible to absorb energy by deforming. Bones shorten and widen when compressed, and lengthen and narrow in tension. WebStiffness and strength are the chief properties of a bone whether it is considered as a structure or as a material. The modulus of elasticity shows how stiff the bone material is. …
