PROBLEM 1:
A standard split-spoon penetration sampler is proposed for a geotechnical field exploration project. Calculate the area ratio of the sampler if its outside and cutting-edge diameter are 45 mm and 40 mm respectively
PROBLEM 2:
A soil sample has a mass of 2290 g and a volume of 0.00115 cu.m. After being completely dried in an oven, the mass of the sample is found to be 2035 g. If Gs=2.68, determine the air content in percent
PROBLEM 3:
A soil sample has a unit weight of 120 pcf and a degree of saturation of 65%. When its degree of saturation is increased to 80%, its unit weight increases to 124 pcf. Determine the saturated unit weight of the soil sample (lb/ft^3 ) if the unit weight of water is 62.35 lb/ft^3

In this problem we want to calculate the electric field due to several charge linear distributions .a) Consider a thin rod of length L. The rod carries a uniform charge density, λ, and total charge Q. Calculate the electric field at a point p that is on the rod’s cylindrical axis of symmetry and a distance d away from the end of the rod. Do this by direct integration. How does your expression be have as L→∞?b) Repeat, with the...

5.  Problem 12.08 (New Project Analysis) You must evaluate the purchase of a proposed spectrometer for the R&D department. The purchase price of the spectrometer including modifications is $140,000, and the equipment will be fully depreciated at the time of purchase. The equipment would be sold after 3 years for $48,000. The equipment would require a $13,000 increase in net operating working capital (spare parts inventory). The project would have no effect on revenues, but it should save the firm $62,000...
