Handed out: 16 February 06 Due: 2 March 06 16.423J/HST515J/ESD.65 Space Biomedical Engineering and Life Support Systems Bone Homework Assignment #2 Bone: The goal of this assignment is to further investigate the changes that age and environmental loading (1G, microgravity, etc.) have on geometry and bone mineral density of bone (modeled as a tubular structure). You are to perform simulations using a computer spreadsheet or Matlab. Credit will be given for discussion, professional work, the process articulated, illustrations , and number answers. Assumption: Long bones can be simulated as hollow tubes, which are subjected in life mainly to bending stresses. Generally, the moment arms do not change with age although load magnitudes do change. Starting conditions for young adult femur shafts. Female outer radius, r o = 1.40cm Male outer radius, r o = 1.70 cm Female inner radius, r i = 0.90 cm Male inner radius, r i = 1.20 cm Assume that remodeling normally increases inner radius at the rate of 0.004 cm/year
