A rectangular building is to be constructed on a site where the soil profile consists of 3m of dense sand overlying a 5m thick layer with an over-consolidation ratio of 1, which overlies rock. The soil properties of the clay are Cc = 0.25, Cr = 0.05, gsat = 18 kN/m3, for the sand gsat = 18 kN/m3, and the water table is 2 m below the soil surface. Determine the settlements when a stress of 100 kPa is applied by the building over an area of 10m × 5 m on the soil surface.
If the tensil testing machine can apply no more than 925 lbs. of force to the specimen, calculate the maximum rod diameter that should be used. (precision 0.000)?
The gate is rectangular with a horizontal width of 2m perpendicular to the paper. For a depth h = 3m of water, calculate the required force exerted by the hydraulic cylinder to keep the gate just closed.
At a specified point on a highway, vehicles are known to arrive according to a Poisson process. Vehicles are counted in 20-second intervals, and vehicle counts are taken in 120 of these time intervals.
Processing begins when the lane reaches capacity, what is the uniform deterministic arrival rate if the vehicle queue is cleared in 35 minutes after vehicles begin to arrive (in veh/min.)?
The herbicide 2,4,D, is applied to a golf course at a rate of 1.2 kg/ha. The organic matter content of the soil is 1%, bulk density is 1.3 g/cm3, and water content is 0.3. a) What fraction of the herbicide is adsorbed, and what fraction is dissolve..
A cross section of a cottage, 20 ft wide, is an isosceles triangle. If the slope of a side is 1.75 and there is a second floor 8 ft above the ground floor, what isthe width of the second floor?
Given s=.30/(60-u), where s is the spacing (space headway) in miles, and u is the speed in miles per hour, derive the relationships u-k, u-q, and q-k. Also, estmate the capacity (qmax) of the roadway.
A worker needs to enter a confined space to tighten the packing on a leaking argon valve. Describe two procedures that could be used to isolate the argon line and valve prior to starting work.
The rigid bar abcd is supported by a pin at B and restrained by identical steel bars at C and D, each of area 250mm 2 . if the temperature is increased by 8 0 C, find out the force P that will cause the bar at c to be stress-free.
Determine the number of man-hours required to form the structure using data from R. S. Means or other appropriate reference. What is the difference between labor cost and labor pro-ductivity?
what is the engineering ethics case related to civil engineering with reference and discuss all the engineering ethics issues which covered the "Engineering etics concepte and cases?
