Write a computer program to calculate slope intercepts and end areas by the coordinate method, given cross-section notes and roadbed design information. Use the program to calculate the slope intercepts for the data of Problem 26.16.
Problem 26.16:
From the following excerpt of field notes, plot the cross section on graph paper and superimpose on it a design template for a 30-ft-wide level roadbed with fill slopes of 2-1/2:1 and a subgrade elevation at centerline of 970.30 ft. Determine the end area graphically by counting squares.
The modulus of elasticity of the sand was determined to be 10,000 kN/m^3 throughout. Using the Schmertmann's method, estimate the settlement of the footing four years after construction, using four 1 meter thick sublayers.
A 2-ft diameter circular pipe has a Manning's n of 0.013 and a bed slope of 2.0 X 10^-3. What is the uniform flow rate in this pipe if it is completely full (Qf) in ft^3/s
For a concrete column that is part of a braced frame, if the column is square, tied, 18 inches per side, 16 feet long, classify the column as slender or non slender
A 50-kg crate is pulled by the constant force P at an angle of 30 deg off the x axis- the crate starts from rest and achieves a speed of 10 m/s in 5 s. the coefficient of kinetic friction between the crate and ground is 0.2. Determine the magnitude o..
The engineering team at Manuels Manufacturing, Inc., is planning to purchase an enterprise resource planning (ERP) system. The software and installation from Vendor A costs $380,000 initially and is expected to increase revenue $125,000 per year ever..
A light rail transit agency operates trains over a 25-km long single-track line. During the peak period, it operates five trains at 15-min headway. Train travels at an average speed of 50 km/hr.
The spillway section is 40 feet high, its crest length is 60 feet and the maximum discharge is 3,000 CFS when the head on the crest of the spillway is 5 feet. Using a model scale of 1:10, calculate the height of the model.
bathtub full of water with small tub floating in it with baby and rock in it. the baby throws rock into tub. will water level rise, fall, or stay the same
Besides irrotation incompressible flow, list 3 physical processes governed by Laplace equation. (feel free to list more, they're a bonus)
Design a Portland cement concrete mix for a loading dock driveway slab. The concrete will be exposed to deicing chemicals and subjected to freezing and thawing in a moist condition. This is severe environmental exposure.
A pipeline 900 ft long discharges freely at a point 200 ft lower than the water surface at intake. The pipe intake projects into the reservoir. The first 600 ft is of 10-in diameter, and the remaining 300 ft is of 6-in diameter.
There has been a significant growth in the use of engineered composites for various engineering applications because of their many advantages over traditional construction materials.
