BIOM 101 Lecture 14: 10-10 BIOM 101
Document Summary
Human skeletal system is 206 bones, connected by soft tissue. Study of mechanical laws related to biological systems. Study of the structure and function of biological systems. Improcing athletic performance and reduction of athletic injuries. Ergonomics and human risk factors, reduction of workplace injuries. Comparative biomechanics ( eg bird flight, fish swimming) Artificial limbs, joints, and orthoses to improve functional movement capability. Biological materials, including cells, are mechanical objects subject to forces because of the world around them. Newto(cid:374)ia(cid:374) (cid:373)e(cid:272)ha(cid:374)i(cid:272)s, newto(cid:374)"s 3 laws of (cid:373)otio(cid:374: body at rest stays at rest, body in motion stays in motion, sum of forces= mass * acceleration, every action has an equal and opposite reaction. Way materials deform in response to load depends on their properties. Stress= = force per unit area= f/a [in units of pressure] Strain, , frational increase in length of material = change in l/ l [no units]
