What does the results of the Compression Test determine? Provide rational for your answer.

he pressure of water at a depth of 10 km in the ocean is measured to be 100 MN/m2. The specific weight of the sea water at the surface is 10.2 kN/m3 while the average bulk modulus is 2.4 x 106 kN/m2. Calculate a) Change in specific volume (dV) between the volume at surface and at the 10 km depth. [4] b) The specific volume [3] c) Specific weight of the sea water at 10 km

Design a square footing for a 18-inch. square column and a superimposed dead load of 200 kips and a live load of 300 kips. The maximum permissible soil pressure is 4000 psf. Use concrete with a design strength of 3 ksi and grade 40 reinforcing bars with yield strength of 40 ksi.

A descending grade of 4.2% intersects an ascending grade of 3% at sta. 12+325 at elevation 14.2 m. These two grades are to be connected by a 260 m vertical parabolic curve. A reinforced concrete culvert pipe is to be constructed with its top 30 cm below the subgrade (or the lowest point of the curve)

What will be the invert elevation of the culvert?

11. Given a concrete mix as follows:

Cement            1 bag               3.15

Water              60 lbs.              1.0

Sand                230 lbs.            2.65 (5% excess moisture)

Gravel             380 lbs.            2.66 (2% excess moisture)

            Determine the quantity of each item that you would use for a 27 cubic foot mixer (you must only use whole bags of cement) weights for sand and gravel, bags for cement and gallons for water (ONE (1) CUBIC FOOT OF WATER = 7.48 GALLONS).

a member in a braced frame supports an axial compressive load and end moments that cause bending about both axes of member. A second order analysis was performed with factored loads and and reduced members stiffnesses to obtain the moments and axial forces. USE LRFD and selet the lightest W shape of A992 steel? Axial=140 k. Mux= 150 ft-kips. Muy=150 ft-kips.

Mux=75 ft-kips. Muy=75 ft-kips.

1. You are a farmer and you are building a fence for your horses.  The fence will have four sides that are all the same.  The total budget for the project is $800 at $200 for each side.  The schedule for the project is 8 days (assume 8 hours per day), estimated at 2 days for each side.  The project started Monday morning and it is now Thursday (of the same week) at the end of the day ‘today’.  You assessed the progress and determined that 25% of the total work has been completed (1 side of the fence).  You have already spent $800 for the work that has been completed as of today.

            Answer the following questions (Please show your work related to all calculations.):

1. What is the planned value as of today?

2. What is the earned value for the project?

3. What is the actual cost for the project?

4. What is the project schedule variance?

5. What is the project cost variance?

6. What is the schedule performance index?

7. Discuss what these metrics mean regarding the performance of the project.

Q1.
