Where is the yield strength on this plot (approximately)? Did the piece of this material used in making this plot undergo an elastic or plastic deformation? Explain. o (stress) E (strain)

7. Carbon steel is tested in uniaxial tension, as shown in the inset schematic, to produce the following stress-strain diagram. 600 500 MPa 600 g 400 400 300 200 200 100 0.005 0.05 0.10 0.15 Strain E Figure 1: Stress vs. strain for plain carbon steel. Note: the inset shows the initial portion of the data, magnified for clarity. a) From the Figure 1, determine the following material properties: (i) elastic modulus, E, (ii) ultimate tensile strength, UTS, (iii) yield stress, oy. b) Label the following regions or points on the figure: (i) fracture point, (ii) plastic region, (iii) elastic region. 8. You wish to design a new bone screw used to hold fractured bone segments together or to hold implants in place. Describe what type of material you would use and what considerations you need to make. 27°F Cloudy Stress (MPa) a

Please answer it within 30 minutes.I will upvote! Problem: An artist creates a solid sculpture made from 8.30 kg of tin. She wishes to create an identical sculpture, using the same mold used to make the original, out of solid lead. What is the mass (in kg) of the lead sculpture? (The density of tin is 7.26 ✕ 103 kg/m3, and that of lead is 11.30 ✕ 103 kg/m3.)
