The soil at a site is shown in Figure P16.12. A slope will be cut to facilitate the construction of a roadway. One possible failure surface is shown in Figure P16.12. Determine the factor of safety. The shear strength parameters were obtained from direct simple shear tests.
A tank is divided into two equal chambers by an internal diaphragm. One chamber containes methane at a pressure of 500 bar and a temperature of 20 C, and the other chamber is evacuated.
A confined aquifer 30 m thick has been pumped from a fully penetrating well at a steady rate of 5000 m3/day for a long time. Drawdown at an observation well 15 m from the pumped well is 3.0 m
A 40-cm straight pipe is used to carry water at 20 degrees C from resevoir A to resevoir B that is 0.7 km away. There is an elevation difference of 9-m between the two resevoirs. Determine the discharge for
If a force of magnitude P is applied to the grip of the clamp, determine the compressive force F that the wood block exerts on the clamp.
You will be analyzing the frame below,which has the same properties as the previous homework:
The secondary clarifier actually produces 3,000 mg/l Xr, but RAS stays at 25% as originally planned. Do F/M, MLVSS and SRT change from what was planned?
Calculate the variation of the glide force and the climb force for the two dislocations as a function of the relative positions of the dislocations (i.e. as a function of θ).
A contractor wants to build a fill at his new construction site. He has two options for purchasing his borrow material. Site A has a soil with a unit weight of 2.5 kN/m3, a moisture content of 14% and a cost of $8 per cubic meter
A more conservative increase from 27.5 mpg in 2011 to 35 mpg by 2020 is supported widely in Washington. California and 13 other states + the District of Columbia hope to increase that stander to 35 mpg by 2017 and 40 mpg by 2020.
At the proportional limit, a 32-mm-thick by 87-mm-wide bar elongates 10.2 mm under an axial load of 532 kN. The bar is 2.4 m long. Poisson%u2019s ratio, , for the material is 0.27.
A building is located 19 ft from the centerline of the inside lane of a curved section of highway whose radius is 400 ft. The road is level and e = 10. Determine the posted speed limit (to the nearest 5 mph) considering the following conditions:
CD triaxial compression test the specimen was consolidated under an effective confining stress
