Write a particular specification for a cut-to-fill earthworks operation for a large sports field. Use the SABS 1200 format. You will have to establish realistic values for the density requirement of the fill, quality requirements and tolerances, method of payment and sufficient pay items. Use SABS 1200 DA as a guide.
Assume that the ground conditions are unknown and could include rock, hard and soft materials. Also assume that the size of the sports field is not known as the Client has not yet decided if he needs a field for soccer, rugby, cricket or hockey, or all four. Note that the project specification will include a geotechnical report and a series of drawings giving all dimensions, slopes, etc.
Three components of an incompressible flow field are given by u=a(x^2-y^2), v unknown, and w=b, where a and b are constants. What must the form of the velocity component v be
The porosity of both media is 0.40, the shape factor for the anthracite is 7.5, and the shape factor for the sand is 6.0. Assume a water temperature of 60 F.
A concrete mix with a 3 inch slump, w/c ratio of 0.50, and sand with a fineness modulus of 2.4 contains 1.700 lb/yd^3 of coarse aggregate. Compute the required weight of coarse aggregate per cubic yard.
List some of the advantages and disadvantages of rectangular primary sedimentation tanks over circular sedimentation tanks which must be considered prior to the selection
write the matlab statements required to calculate and print out the squares of al the even integers between 0 and 50. create a table consisting of each integer and its square, with appropriate labels over each colum.
A 2-kg block slides on the smooth circular path (Quadrant One of full circle, block moving left to right). If it is released from rest when theta=0 degrees, determine the force it exerts on the path when it arrives at Point A
Two Tangents intersect at a PI Station of 35+33.24 whose coordinates are N=10349.64 feet and E= 10436.79 feet. The Intersection angle (I) = 20°15'42" Right, and the azimuth of the back Tangent is 23°14'32". (This azimuth is from the PC to the PI.)
The maintenance costs begin in 31st year at $300,000 annually. How much must be deposited now if the fund will earn 5% interest. How much does this change if the interest rate is 4%
The variable capacitor in the tuner of an AM radio has a capacitance of 135pF. When the radio is tuned to a station at 550kHz what is the capacitance for station at 1600kHz.
The bracket is subjected to the two forces shown. Express each force in Cartesian vector form and then determine the resultant force FR. Find the magnitude and coordinate direction angles of the resultant force.
A fan is to be selected to ventilate a bathroom whose dimensions are 2 m x 3 m x 3 m. The air velocity is not to exceed 8 m/s to minimize vibration and noise.
A Proctor compaction test in the laboratory on a borrow pit soil gives a maximum dry unit weight of 19 kN/m3 and optimum water content of 11.5%. The bulk unit weight and water content of the soil in the borrow pit are 17.2 kN/m3
