A geotechnical report has suggested an allowable bearing pressure of 200kPa. Determine the minimum size of the pad footing 2 metres wide for a steel column if a factor of safety of 2.0 is recommended (include an estimate of self weight of the footing in your calculations). The total load of the column is 447.644kN
consider a spacecraft that is positioned directly between the earth and moon.the mass of the moon's is approximately 7.35 X10^22 kg, and at the instant under consideration, the moon is 3.8 X 10^8 km from earth.
What is the maximum safe speed around the curve? If the speed limit on the roadway is 60mph, what action should be taken by the engineer?
The pump graphs are given to us, and I'm asked to determine possible lengths and diameters of the pipe to meet two requirments. The system can have multiple outputs in order to satisfy the needs, but they must be occuring at the same time.
The motor has an efficiency of 80%. It operates at 240V AC. A 12" diameter drum is attached to the gearbox output shaft, and a wire rope is wrapped around the drum to act as a winch. The winch is used to raise bucket of raw material in a factory.
How much of a reduction in the automobile emission rate would be required to achieve the maximum eight-hour average NAAQS for CO at steady state 9ppmv (10.3 mg/m3)?
The column is constructed from high-strength concrete and four A-36 steel reinforcing rods. If it is subjected to an axial force of 37.5 kN , determine the required diameter of each rod so that one-fourth of the load is carried by the concrete
Discuss the role of each physical, chemical and biological unit operations and processes employed in the wastewater treatment facility. If this treatment facility is required to supply class A recycle water to those industries for non-potable use
A pool of benzene is ignited on the floor of a large industrial building. The total area covered by the Kerosene pool is 6 meters square (Note that this is considered a large pool D>0.2 meters). Combustion efficiency is 70%. Estimate the plume mas..
Suppose that all the dislocations in 1000 mm^3 (1 cm^3) were somehow removed and linked together end-to-end. How far (in miles) would this chain extend
Water flows upward in a vertical 12" pipe at the rate of 7.85 cfs. At point A in the pipe the pressure is 30.5 psi. At B, 15 ft above A, the diameter is 24" and the lost head A to B equals 6 ft.
A large rock became visible to a driver at a distance of 175 ft. Assuming a perception-reaction time of 0.8s, an initial speed of 42 mph, a coefficient of friction equal to 0.5, and a level roadway, calculate the speed at impact.
The initial schedule called for 500 feet of pipeline to be installed each week, with the total construction cost projected to be $25 million. After 8 weeks, 4750' of pipeline has been installed at a cost of $11.25 million.
