1. For a piece of material, the steady state flow of material across its thickness is 180 x 10-3 kg/m2-hr. If the concentration on the high side of the material is 2.0 kg/m3 and is 0.22 kg/m3 on the low side of the material, calculate the thickness of the material. D = 1.03 x 10-10 m2/sec.

2. Calculate the dimensions of the indentation in a metal with a Vickers Hardness (HV) number of 525 caused by an applied load of 925 kg.

3. Calculate the engineering strain for a beam of stainless steel under tensile stress with an original length of 7.85 inches and a gage length of 9.66 inches.

4. Eight moles of solid SiO occupies a cube which measures 2.25 inches on each side. Calculate the density of SiO in g/cm3.

5. A 70 wt% Cu - 30 wt% Zn alloy rod with a manufactured length of 12 mm has been elongated to 13.5 mm. Determine the hardness and tensile strength of the elongated rod.

6. What is the minimum manganese content in a Fe-Mn-0.05 alloy in order for the alloy to have a Charpy V-notch impact energy of at least 50 joules at 0C.

7. Calculate the fraction of a 100 KeV x-ray beam remaining after it is transmitted through a 7.5 mm thick plate of iron.
