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.

1a. What would be the effect on your calculations of specific
heat of the metal if there was heat lost while transferring the
metal? Explain why. 1b. What would be the effect on your
calculation of specific heat of the metal if the metal you heated
was wet, and contained 2% water by weight when you poured it into
the calorimeter? Explain why. 1c. What would be the effect on your
calculations on specific heat of the metal if you...

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...

e are choosing material for a round rod. The material must be a
metal or alloy. The length of the rod must be close to 1 m, and its
cross-sectional diameter must be between 1 mm and 3 mm. Its natural
frequency of vibration, f, should be as low as possible.
(a) Clearly list the constraints, objective, and free variables.
(b) What is the performance index of the material? (c) What are the
best 2 material candidates?

The composite shaft shown in the figure consists of two steel pipes that are connected at flange B and securely attached to rigid walls at A and C. Steel pipe (1) has an outside diameter of 158 mm and a wall thickness of 6 mm. Steel pipe (2) has an outside diameter of 114 mm and a wall thickness of 4 mm. Both pipes are 3.5 m long and have a shear modulus of 80 GPa. If a concentrated torque...
