At Bob’s Discount Materials Testing Emporium of Wonders, a client looking to save a few dollars wanted a test conducted in order to find the Poisson’s Ratio for a material with elastic modulus, E = 70 GPa. A 200-mm long sample with circular cross-section (diameter = 20 mm) was subjected to an elastic axial load of 60 kN. Due to funding cuts and general apathy by the staff, the equipment isn’t available to measure axial strain while in the testing apparatus so it must be calculated. Under load, the diameter was measured (using a cheap Harbor Freight micrometer) and found to have contracted by 0.015 mm. As an overworked, unpaid intern on Bob’s staff, sigh, roll your eyes, and begrudgingly calculate the following values: a. Lateral Strain, εlat.
b. Axial Strain, εaxial.
c. Poisson's Ratio, V = .
d. Shear Modulus, G = .GPa

An insulated tank truck containing 50,000 pounds of double-distilled, deionized water at 30 °c is pumped into a closed, refrigerated storage tank maintained at 5 °c in a facility located on top of mount mitchell, north carolina (elevation 6,684 feet & average july temperature of 84 °f). a)-determine the volume of the storage tank required to hold the purified water. b)- determine the initial and final pressure differences that must be overcome by a liquid pump assuming the storage tank initially contains air at 5 °c. assume the air is slowly bled out of the storage tank during the water transfer c.) during a routine operation today, the tank is slightly ruptured by a stainless steel pipe and a water acrosol of droplets begins to spray out of the storage tank. state all assumptions and determine the internal pressure within the water droplets produced
