1.The total volume of a soil specimen is 120 cm3 and its total mass is 220g. Specimen porosity is 0.4 and specific gravity of solids is 2.66 Determine the following: (a) water content, (b) void ratio, (c) degree of saturation, and (d) dry density.
2.A saturated soil has a void ratio of 0.7 Specific gravity of solids in this soil is 2.67
Determine (a) the saturated unit weight, and (b) dry unit weight. Use units of ft and lb.
Estimate the effective friction angle for the sand (assume c' = 0). Calculate the sand's shear strength (τf) on a horizontal plane at depths of the 20 ft and 50 ft.
The line of sight of a level falls at a rate if 0.122ft/ 100 ft when the level bubble is centered. A backsight of 4.782 is taken on point A, which is at 75 ft from the level. the elevation of a is 425.238 ft.
For the fully developed flow of water in a smooth 0.15-m pipe at a rate of 0:006m3/s, determine the thickness of a. the laminar sublayer; b. the buffer layer; c. the turbulent core.
At the proportional limit, a 32-mm-thick by 87-mm-wide bar elongates 10.2 mm under an axial load of 532 kN. The bar is 2.4 m long. Poisson%u2019s ratio, , for the material is 0.27.
Calculate the additional stress as a function of depth that a temporary construction wall , like that shown in Figure As 1, must take as the result of a crane sustained in the zone above it.
The compound interest formula is F=P(1+i)n where F is the total amount due, P is the initial cost or amount of money, i is the interest rate, and n is the number of periods interest is computed. 1.A student purchases a $1400 laptop computer for sc..
The saturated unit weight (sat) of the sand is 20.0 kN/m3 and the anticipated depth to water in the well during pumping is 20 m below ground surface.
Compute the maximum acceptable tensile service load T that may act on a single angle L6x4x3/4 that is welded along only one leg to a gusset plate; thus, there are no holes. The service load is three times the dead load. Solve for a0 A36 steel.
A transit was set at point M and a leveling rod was held vertically at point N. The horizontal cross line of the telescope was inclined so the reading of the horizontal cross line on the rod was 12 ft.

How many hours should it take an articulated wheel loader equipped with a 4 yd bucket to load 3000 cu yd of gravel from a stockpike into rail cars if the average haul distance is 300 ft one way
An unknown fluid flows through a horizontal 35-mm-diameter pipe with a Reynolds number of 100,000 and a density of 680 kg/m3. The pressure drop across a 21-mm-diameter nozzle meter placed in the pipe is 4.2 kPa.
