Determine the value of Po, as a funciton of H, for these two investment alternatives to be equivalent at an interest rate of i=15% per year.
What difference does the tightening of bolt in the friction grip joint make to the load at first slip and the failure load.
Estimate the effective friction angle for the sand (assume c' = 0). Calculate the sand's shear strength (τf) on a horizontal plane at depths of the 20 ft and 50 ft.
Water with a static pressure of 1.96kN/M 2 flows through an 800 mm diameter pipe. A pitot tube pressure gage in this pipe reads a pressure of 5.88 kN/M 2 . How do you determine the volume flow rate (Q) of the water? (Q = 1.40 M^3/sec, V=2.79 M/se..
Samples of 20 rivets for a steel structure are checked for quality every hour. The probability of finding a bad rivet that has to be scrapped is 1%.assume that x is the number of parts in the sample of 20 that have to be scrapped.
A four-lane urban freeway (two lanes in each direction) is located on rolling terrain and has 12-ft lanes, no lateral obstructions within 6 ft of the pavement edges, and an interchange every 2 miles.
Include immediate and consolidation settlements, but ignore secondary compression. In your calculation, use three sublayers with thicknesses of 4 ft, 8 ft and 16 ft for the top, middle and bottom layers. Ignore any settlement caused by the dense s..
Assuming that the velocity variation within the main channel and the floodplain subsections is much smaller than the change in mean velocities between subsections, find the value of the kinetic energy correction coefficient.
Determine: a) the height of the water, with respect to the base of each standpipe, and b) the effective stress at the depth of each standpipe, at the following times:
Assume you are observing traffic in a single lane of a highway at a specific location. you measure the average headway and average spacing of passing vehicles as 3 seconds and 150 ft, respectively. calculate the flow, average speed, and density of..
Devise a appropriate management system that you as a commercial manager for the contractor would recommend to the project team for use on a construction or building contract.
To float a 160 pound man using helium balloons (assume 0.52 cubic feet per inflated balloon). How many balloons would it take? Assume density of air is 1.29 kg/cubic meter and the density of helium is 0.179 kg/cubic meter.
What is the minimum distance from the stalled car at which the driver could apply the brakes and still stop before hitting it? Assume coefficient of rolling resistance of 0.013.
