Final answer:
The load resistance for bone is least for tension, most for compression, and intermediate for shear. Young's modulus is used to measure bone rigidity and strength, with bone demonstrating high rigidity and exceptional shear modulus.
Step-by-step explanation:
The order of load resistance for bone is least for tension, most for compression, and in between for shear load resistance. When discussing the rigidity and strength of bones, the concept of Young's modulus is relevant. Bone's Young's moduli for tension and compression can differ, but they are averaged for general understanding. Interestingly, bones are quite rigid and do not bend or compress significantly under normal physical activity, which is a testament to its rigidity and load-bearing capabilities.
Upon examining the shear modulus, it is observed that bone has a shear modulus that is greater than its Young's modulus, making it an exception among materials. This unique property allows for bones to support loads comparable to materials like concrete and steel, mainly due to its ability to withstand twisting and bending rather than just compression.
