A site investigation was conducted to determine the suitability of the material from a borrow pit for a gravel road construction. A 174.33 mm (internal diameter) thin-walled sampling tube was pushed into the bottom of a trial pit and a 218.72 mm long undisturbed specimen, weighing 4802.9 g, was obtained. When dried in the oven, the specimen weighed 4382.99 g. The specific gravity of the soil grains was measured and found to be Gs = 2.66, Determine the following:

the total volume of the soil
the volume of the solids
the volume of water
the volume of voids
the volume of air
the total mass of the soil
the mass of the solids
the mass of water
find the void ratio,
water content,
degree of saturation,
bulk density
and dry density.
The order in which you determine these variables is up to you. You will be writing down your answers in the following 13 questions (one variable at a time).

Use units of Mg for masses and m for lengths.

You may take the density of water to be 1.0 Mg.m3

An investigation is to be conducted to determine the source of reduction in yield of a certain chemical product. It is known that the loss in yield occurs in the mother liquor, that is, the material removed at the filtration stage. It is hypothesized that different blend methods of the original material might result in different yield reductions at the mother liquor stage. T1 is the current blending procedure in use, and the chemical engineers would like to compare this...

a) The soil from a borrow pit is at a total density of 1.8 t/m3 and a water content of 12%. It is desired to construct a road subgrade with a compacted total density of 2 t/m3 at a water content of 17%. Determine the quantity of soil (dry mass in tonnes) to be excavated from the barrow pit and the amount of water (in litres) to be added for every 1 m3 of compacted soil in the embankment. (Assume...

An investigation is conducted to determine if the exposure of women to atomic fallout influences the rate of birth defects. A sample of 500 children born to mothers who were exposed to the atomic explosion in Hiroshima was studied. A sample of 400 children from a Japanese island far removed from the site of the atomic explosion formed the control group. Suppose that the following data and R output for the incidence of birth defects were obtained. Expected counts are...

An investigation was conducted to determine the source of reduction in yield of a certain chemical product. It was known that the loss in yield occurred in the mother liquor, that is, the material removed at the filtration stage. It was thought that different blends of the original material might result in different yield reductions at the mother liquor stage. The following are the percent reductions for 3 batches at each of 4 preselected blends: Blend 1234 25.6 25.2 20.8...

During construction, field tests were conducted to assess the suitability of the column to withstand a safe buckling load of 2.5 kN assuming a factor of safety 4 using two different hollow columns made up of steel and concrete. Both columns have same cross section but varying length and different support conditions. Steel column of length 3 m having external diameter 40 mm was tested with one end fixed and the other end hinged, when subjected to a compressive stress...

A. Calculate the price of pit-run gravel delivered to the site per cubic yard (bank measure) based on the following data: The pit is located 10 miles from the site. Trucks cost $43.75 per hour including fuel and maintenance; they have 12 cubic yards (loose material) capacity and travel at an average speed of 30 miles per hour. The swell factor for this material is 15%. Trucks take 5 minutes to unload at the site. The loader costs $82.50 per...
