The mechanical properties of a metal may be improved by incorporating fine particles of its oxide. Given that the moduli of elasticity of the metal and oxide are, respectively, 60 GPa and 380 GPa, what is the (a) upper-bound, and (b) lower-bound modulus of elasticity values (in GPa) for a composite that has a composition of 33 vol% of oxide particles.

There is complete security in their country. Neither traveler nor inhabitant in it has anything to fear from robbers or men of violence. They do not confiscate the property of any white man who dies in their country, even if it be uncounted wealth. On the contrary, they give it into the charge of some trustworthy person among the whites, until their rightful heir takes possession of it. They are careful to observe the hours of prayer, and assiduous in attending them in congregations and in bringing up their children to them. - Ibn Battuta "Travels in Asia and Africa," 1325-1354 Using the prompt, which explains why Timbuktu became such an important urban center in the Mali kingdom?

The Reynolds number is a dimensionless quantity used in fluid mechanics. It is defined as:where d is the pipe diameter, v is the fluid velocity, is the fluid density, and is the fluid viscosity. In American Engineering units (ft, sec, lbm), what are the units of the viscosity? Hint, all the units should cancel out to produce the dimensionless Reynolds number.

A dry sample of sand is placed in a container having a volume of 0.3 ft3. The dry weight of the sample is 31 lb. Water is carefully added to the container so not to disturb the condition of the sand. When the container is filled, the combined weight of soil plus water is 38.2 lb. Calculate: a) the void ratio of the soil in the container, b) the specific gravity of the soil particles, c) the wet and the dry unit weights specifying their units.
