1. On the stress-strain curve below, label elastic deformation, plastic deformation, yield stress, ultimate tensile stress, and rupture stress. 2. Three materials 1) long bone, 2) dentin, and 3) knee meniscus, which have Young's modulus of 20,000MPa,2,000MPa, and 200MPa, respectively. 1. How much strain energy per unit volume is required to deform each of these materials to a strain of 0.1% ? 2. How much strain energy is stored in each of these materials per unit volume, if they are subject to the stress of 40MPa ? Which is the most brittle tissue, and which is the most compliant tissue? 3. Use one example to explain the effects of mechanics on cell/tissue behaviors. 4. Briefly explain how biomedical instruments work in general. You can use a graph to help you explain. 5. List five biomedical instruments and explain what the sensors are and what signal they sense, respectively. 6. Briefly explain what properties x-ray has that make it particularly useful in bioimaging compared to other rays
