Study Notes
Types of Loads and Stresses
- Compressive load results in compression or squeezing
- Tensile load results in stretching
- Shear load results in sliding
- Torsional load results in twisting
- Bending load results in a combination of compressive, tensile, and shear stresses
Effects of Loads on Bones and Muscles
- Compressive load causes compressive stress
- Muscles and origins and insertions of the muscles (on the bone) experience compressive stress
- Shear load causes shear stress
- Bones are primarily designed to resist compressive stress from axial loading
Bending Loads
- Bending load results in compressive stress on the inner side of the bend
- Bending load results in tensile stress on the outer side of the bend
- Bending load results in shear stress along the neutral axis
- 3-point bending: Bending caused by a combination of three forces (e.g., "dashboard injury")
Ligaments and Tendons
- Ligaments and tendons are subjected to tensile load pattern
- Ligaments and tendons experience tensile stress
Other Types of Loads and Stresses
- Torsional load on the pitcher's humerus causes spiral fracture
- Spiral fracture caused by torsional load on the femur
