1.Lines of levels were run requiring (n) instrument setups. If the road reading for each backsight and foresight has a standard deviation of +-0.005 ft what is the standard deviation for n=40?

2.A four-wheel tractor whose operating weight is 47,877 lb is pulled up a road whose slope is +3.5% at a uniform speed. If the average tension in the towing cable is 4,860lb, what is the rolling resistance of the road?

3.Determine the dynamic viscosity of glycerin at 85 degrees Farenheit. Express your answer in both SI and BG Units.

4.Two parallel plates, one moving at 4m/s and the other fixed, are seperated by a 5mm thick layer of oil of specific gravity 0.80 and kinematic viscocity 1.25 X 10^-4 m2/s. What is the average shear stress in the oil?
