2 - What is the appropriate device for diagnosing each of the following and why? A- The aluminum plate is coated with a nano-solution. b- A colloidal sample containing nano-solutions. C- Study of the microstructure of the surface of a sample of %3D iron.

As an R&D engineer, your input is requested to design an enhanced device that will be permanently implanted to repair the load-bearing function of a joint. Details on the candidate metals are presented here: Material SS 316 type Pure Ti Density (p) Yield stress (g/cm³) (MPa) 8 4.5 Ti6A14V 4 (F136) 190 140 795 Maximum elongation (%) 40 15 10 Elastic modulus (GPa) 190 110 114 Lo Shess leve O What force can each of the materials carry without permanent deformation? Which one offers better properties as a load-bearing implant? Explain. Describe the primary consequences of choosing the wrong material; consider in your answer the effect of density, yield stress, elongation, and Young's modulus on the implant's performance.

Some of the metals possess a body-centered crystal structure. Which of the following statements is correct about the structure? a. There are atoms found at the center of each face of the cube. b. It has a density lower than scc. c. The corner atoms touch the center atom but not each other. d. It has a packing efficiency (74%) greater than scc and bcc.
