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
Explore the concept of mechanical load and stress, biomechanics, the stress-strain curve, mechanical properties of tissues, and the concept of injury as they relate to the human body. Learn about the five types of mechanical load and the effects of applied mechanical load on the body's motion and segments.
