Question
Bone is considered to be, meaning that it does not have the same mechanical properties in every direction. Bone is considered to be weakest against forces. Isotropic; compression Isotropic; shear Anisotropic; compression Anisotropic; shear identify the true statement. Increasing the surface area over which a force is distributed decreases the amount of stress acting on the surface. Decreasing the surface area over which a force is distributed decreases the amount of stress acting on the surface. Both A and B are true. Neither A nor B is true. Bone is strongest in resisting: Tensile stress Shear stress Compressive stress Bone is equally strong in resisting all types of stress. Bone is weakest in resisting: Tensile stress Shear stress Compressive stress Bone is equally strong in resisting all types of stress. Ligaments are less stiff and slightly weaker than tendons because: Ligaments have more elastin and less-aligned collagen fibers Ligaments have less elastin and more-aligned collagen fibers Ligaments have a different type of collagen fiber Ligaments have randomly arranged collagen fibers Which of the below anatomical structures has a high concentration of fibrous (fibrocartilage)? Intervertebral discs Menisci Pubic symphysis A and B A, B, and CExplanation / Answer
9. D Anisotropic and shear
10. A is true. Increasing the surface area will decrease the stress on the surface.
11.C. Bone is strongest in resisting compressive stress.
12.B It is weakest in shear stress.
13.B.Ligaments have less elastin and more aligned collagen fibres
14.E. A,B and C. Intervertebral disc forms a fibrocartilaginous joint between the two vertebrae as a disk, Menisci are also fibrocartilaginous structures in the human knee and wrist. Pubic symphysis is also a joint made of fibrocartilage present at th epubic part of abdomen.
