A soil, 150mm x 150mm x 20mm high, is subjected to simple shear deformation. The normal force in the Z direction is 1 kN and the shear force is 0.5 kN. The displacements at the top of the soil in the X and Y directions are delta x = 1mm and delta z = 1 mm.
Calculate:
a) The shear and normal stress
b) The axial and shear strains
The P.C. of a 3 degree curve, whose degree is based on a chord of100 ft. arc, is at Sta. 19+39.60 and the P.T is at Sta. 25+64.60. Calculate the deflection angle from the tangent at the P.C to each100-foot station on the curve and to the P.T.
Water flows over a dam. Assume the volume flowrate per unit length q along the dam is a function of the head h , width b, acceleration of gravity g, f luid density and the fluid viscosity. Determine a complete set of dimensionless parameters
An 8.5 m compacted fill is to be placed over the soil profile. Consolidation tests on samples from points A and B produced the following results. a) Calculate the consolidation settlement caused by the weight of this fill.
A one-story, 50-m wide X 90-m long manufacturing building is to be built on a site underlain by medium dense to dense silty sand with occasional gravel. This soil probably has better than-average engineering properties and average uniformity.
A rural town with sewered population of 4,500 has a daily wastewater flow of 1,590 m3/day with an average BOD of 280 mg/L including industrial wastes. The industrial discharges to the municipal sewers are 57 m3/day at 1,800 mg/L BOD
Water in the amount of 1 lb is contained in a rigid closed tank. Initially the water has a quality of 0.4 at a pressure of 10 lbf/in2. Through a stirrer, work is provided to the water in the tank until the pressure quadruples.
To achive a specific level of disinfection a water treatment plant operator determines the" Ct" value 180mg min/l is necessary with units for disinfectant concentration C in mg/l and disinfectant contact time t in minutes
Draw the influence line for the shear in panel CD of the girder. Determine the maximum negative live shear in panel CD due to a uniform live load of 500 lb/ft action on the top beams.
A 5000 m3/day wastewater treatment plant discharges to a river with a minimum drought flow of 140 m3/min (upstream of outfall) a)What total allowable BOD (kg/day) could be discharged by the plant if the BOD in the river after initial dilution must ..
A rigid 1ft^3 vessel contains R-134a originally at -20F and 27.7% quality. The refrigerant is then heated until its temperature is 100F. Calculate the heat transfer required to do this, in Btu.
At the end of the first 5 years, the company upgraded the analyzer at a cost of $10,000. Following the upgrade the lab purchased another 5 year maintanence contract for $1000 a year, payable at the end of each year.
the water is subjected to a 100 fold increase in pressure. determine the initial weight and final density of the water if the volume decreases by .545 ft ^3.
