Hydroxyapatite minerals provide hardness and resistance to which type of stress?

Explanation:
The main idea is that bone’s mineral component, hydroxyapatite, provides hardness and strong resistance to compressive forces. When you bear weight or press down, bones are mainly under compression, and the rigid hydroxyapatite crystals help push back against that squeezing without deforming much. The flexible collagen matrix in bone handles pulling apart forces (tension) and helps prevent cracks from spreading, while twisting (torsion) or sliding forces (shear) involve a mix of stresses that rely on both minerals and collagen for resistance. So, hydroxyapatite’s strength is most closely aligned with resisting compression.
