1- In the graphics used in material selection, the size of the material bubbles is displayed on the horizontal/vertical axes It also appears to be getting longer. Briefly explain the reason for this separately for metals, ceramics, composites and polymers (You can use the Modulus-Strength curve when making the necessary explanations). (20p) 2- a) As an engineer, you are asked to design a furnace that can be used up to 1200 C. Select the refractory materials that could be candidates and briefly explain them. (10p) (M: a1/2/y) b) We would like to benefit from your expertise in material selection in order to design an internally cooled casting mold in a casting workshop. Explain your candidate material or material groups in detail. (10p) 3- Although it is one of the types of injuries that occur as a result of automobile accidents and is seen at statistically low rates, pelvic fractures are a serious type of injury. As a material scientist and designer, explain the steps to be followed in selecting the pelvis protector that can be used in automobiles, you can use Ashby diagrams. (20p) 4- You are asked to design a piston for an internal combustion engine that can operate at high temperatures. Using Ashby diagrams and your material knowledge, explain in detail which material(s) you chose and why. (20p) 5- You are expected to design a "cantilever" to be used in atomic force microscopy (AFM). This designed structure is expected to carry a load of at least 100 MPa. You can use E1/2/ as the index. Please describe the suitable material candidates and why you chose them. 1- In the graphics used in material selection, the size of the material bubbles is displayed on the horizontal/vertical axes It also appears to be getting longer.
