How much difference in the computed settlements is there in Problem 8.44 if the Westergaard theory is used instead of Boussinesq theory ?
Problem 8.44
How would the estimated settlement under the center of a 3 x 3 m square footing compare with the settlement of the 3 m wide strip footing in the previous problem, assuming soil conditions were the same? Assume the footing is flexible enough to provide uniform contact pressure to the soil.
determine the pile head deflection at the working load. In APILES, select option 1, stiff clay, and input the effective unit weight of the soil when prompted. APILES creates a text fi le named apiles. txt in the folder that contains APILES. You ca..
A 5 km2 lake does not have a defined input but receives runoff from its watershed (25 km2). The area receives 60 cm/yr in precipitation. Evaporation from the lake surface is 10 cm/yr with watershed evapotranspiration of 20 cm/yr.
A hollow magnesium shaft is rigidly bonded to a solid steel shaft and rigidly mounted between two supports. A torque of 500 NA·m is applied at the junction between the two shafts. What is the maximum shear stress in the magnesium?

A particle moves along the positive x-axis with an acceleration in meters per second squared which increases linearly with x expressed in millimeters, as shown on the graph for an interval of its motion.
A major relining of the combustion vessel will occur during the fifth year at a cost of $30,000. If the interest rate is 15% per year, what is the lump-sum equivalent cost of this project at the present time
A wastewater treatment plant has two rectangular primary settling tanks, each 40 ft long, 12 ft wide, and 7 ft deep. The effulent weir length in each tank is 45 ft. The average daily wastewater flow is 387,000 gal.
Calculate the critical value of the mechanical potential energy release rate Q at fracture and hence the plane strain fracture toughness Kic of the alloy. All testpieces were 25 mm thick. For the alloy, Young's modulus, E = 70 GPa and Poisson&..
The PI is at station 250+50, the design speed is 65mi/h, and a maximum superelevation of 0.07 ft/ft is to be used. If the central angle of the curve is 38 degrees, design a curve for the highway by computing the radius and stationing of PC and PT.
