Which one of the following stresses would be most likely to cause a bone to fracture?
A. Tensile stress
B. Sheer stress
C. Bulk stress
D. Compressive stress
Explain?
Answer:
B. Sheer stress
Reason: Tensile stress tries to stretch the bone, which usually doesnt result in a fracture.
Compressive stress also falls in the same category as tensile stress. If applied in large amounts results in shattering of the bone rather than a simple fracture.
Bulk stress is just an improved compressive stress.
Shear stress tries to move one end of the bone out of place leaving the other end at the same point. This results in a fracture at some point midway in the bone.
