HSS 2104 Lecture Notes - Lecture 1: Compressive Stress, Work Hardening, Calcaneus
Lecture 1 introduction mechanical properties of materials biomechanics of bone. Biomechanics: science of forces acting upon & w/in biological structure & effects produced by such forces, laws of physics in analysis of biological & physiological systems, movement by body segments, interrelationship b/w force & motion. Occupational biomechanics: mechanical behavior of musculoskeletal system & component tissues when physical work is performed, physical interaction of workers w/ tools, machines, materials, goal enhance worker performance, minimize risk of msk injury over working life. Ergonomics: systematic & rational means of fitting work to individual, development of general principles that govern interaction of people & working enviro to improve worker performance & safety. Mechanical properties of materials: ensure material & design of structure are safe against combined effects of applied forces & movement, strength & deformation of material, determining strength of structure. Deformation: relative displacement of 2 points w/in a body causing change in dimensions, dependent on.
