A cutting 9 m deep is to be excavated in saturated clay of unit weight 19 kN/m3. The design shear strength parameters are cu = 30 kN/ m2 and fu = 0. A hard stratum underlies the clay at a depth of 11 m below ground level. Using Taylor's stability coefficients, determine the slope angle at which failure would occur. What is the allowable slope angle if a factor of safety of 1.2 is specified?
Measure the distance PA, PB, PC etc. from p to various point with chain or tape and plot them to scale along the co responding rays. Join the points a, b, c, etc. to give outline of survey.
What is the definition of a customer? What are some examples of internal and external customers? Is the measurement of customer satisfaction different for internal customers than for external customers?
The testing machin that covers the right range of load is to be chosen. it is expected to load the material up to a strains of 3%. if th material must remain elastic over that range, what would be the maximum load
You are to assume that seawater at 77oF will be used in the tank and the curved portion forms a quarter of a circle. The tank is open to the atmosphere. The overall height, h2, is 20ft deep. The radius of the curve, R, is 5ft. The width of the..
rom a photograph one observes that on a level section of highway 10% of the vehicles are trucks, 90% are cars, and that there are 50 vehicles per mile of highway. The trucks travel at 40 mph, and the cars at 50 mph.
Determine the axial and hoop stresses at the lower end of the vessel. A standpipe 12 ft in diameter and 50 ft tall is being con- structed for use as a storage tank for water with a specific weight of 62.4 lb/ft3. The wall thickness of the vessel is..
At an axial load of 23 kN, a 40-mm-wide by 10-mm-thick polyimide polymer bar elongates 2.7 mm while the bar width contracts 0.17 mm. The bar is 240 mm long. At the 23-kN load, the stress in the polymer bar is less than its proportional limit.
Calculate the pressure, and the piezometric head at the free surface, at both interfaces, and at the tank bottom. Take the elevation datum at the bottom of the tank.
If the water vapor is removed from the upper tank so that the concentration there remains nearly zero, what mass of water vapor diffuses through the tube each hour?
If, on 8/1/2019, 3-year municipal bonds with an AA- rating and a coupon rate of 6.50% (payable semiannually) are selling for $100.00, what would be the fair market value of the 300 Whittier bonds (not including the 8/1/2019 coupon payment)
Estimate the critical pressure of a mixture of methane and n-hexane if the critical temperature of the mixture is known to be 200 F. Compare your answer with the critical pressures of pure methane and pure n-hexane.
Cable AC is 70 ft long, and the tension i nthe cable is 5250 lb. Determine the x, y, and z components of the force exerted by the cavle on the anchor C. Also, find the angles theta-x, theta-y, and theta-z defining the direction of the force.
