Separate triaxial compression tests are performed on identical soil samples. The soil is a saturated mixed soil. Both tests follow the procedure for consolidated-undrained conditions. At failure, the respective minor and major principal stress values are 20 kPa and 46 kPa for one and 40 kPa and 80 kPa for sample two. From these data, determine the value for (phi)cu and the cohesion intercept c on the Mohr's circle shear stress coordinate. (This problem can be solved graphically using Mohr's circle).
It the mean annual runoff of a drainage basin of 10000 km^2 is 140 m^3/s, and the average annual precipitation is 105 cm, estimate the ET losses for the area in 1 year. What are your assumptions
The pins on the frame at B and C each have a diameter of 0.25 in. If these pins are subjected to double shear, determine the average shear stress in each pin.
Calculate and plot the distribution of total and effective vertical stresses as well as pore-water pressure with depth from the ground surface up to the bedrock surface.
Long Line: the slope distance and zenith angle measured from point a to point b were 17,685.20 ftand 93degrees 13' 46" . The instrument and reflector heights were equal. If the elevation of the point A is 1854.43 ft above the MSL Datum
Assume that (t) is givenin degrees, and write the matlab statement to evaluate tan (t) aslong as the magnitude of cos(t) is greater then or equal to(10^-20). If the magnitude of cos(t) less then (10^-10,
Find the time for one complete cycle of this motion if the spring constant is 21 N/m. (Assume that once the pendulum ball hits the spring there is no effect due to the vertical movement of the ball.)
For an elevated storage tank , if the minimum allowable pressure = 300 kPa, Height of pipe system at low-pressure service location = 6 m, and head loss from tank to service location: average daily conditions = 11 m
A small community wishes to construct an activated sludge wastewater treatment plant to treat their wastewater. the wastewater from the community has an average flow rate of 0.0022 m^3/s (190 m^3/day) and an influent substrate concentration of 250 mg..
is fabricated of two 300 mm X 25 mm flange plates and a 800 mm X 16 mm web plate. the plates are joined by four fillet welds that run continuously for the length of the girder. each weld has an allowable load in shear of 920 kN/m.
If an embankment is placed that adds an average additional stress of 32psi to the clay, compare the settlement from the laboratory consolidation test to the settlement from the estimated field consolidation curve.
The angle of the release is 30 degrees. Determine the horizontal distance the shot travels from the point of release to the point where it hits the ground.
The evaporation rate from the surface of a 3,650-acre lake is 100 acre-ft/day. Estimate the depth change in the lake in feet during a 1-year period if the net inflow to the lake is 25 cfs. Is the depth increasing or decreasing
