1a. Spheroidite steel is a good example of Metal Matrix Composite material. What are the matrix material and the dispersed phase acting as a reinforcing agent?

1b. Name one material that is commonly used as the fibers in fiber reinforced composites.

2a. In metals increasing “imperfections” e.g. grain boundaries, dislocations, vacancies in the material will increase or decrease the resistivity of that material? Briefly explain why.

2b. Does the resistivity of a copper increase or decrease when it is heated to a higher temperature? Briefly states why.

Charlotte spends her income of $2400 on clothing (good x), and the composite good (good y ). The utility Charlotte receives from consuming a basket of clothing and the composite good is, U(x, y ) = 2√ x + y 300. The corresponding marginal utilities are, MUx = 1 √ x and MUy = 1/ 300. (c) Find Charlotte’s optimal consumption basket when the price of clothing is Px1 = $50, and the price of the composite good is Py...
