A -2.8% grade line meets a +3.6% grade line at station 125+00 at elevation of 1631.04. Assuming a length of curve is 650feet, compute the elevation and station of the BVC (PVC) and the EVC (PVT).
The flow depth and velocity before the jumo are 0.8 m and 7 m/s respectively. The flow depth and velocity after the jump are 2.46 m and 2.28 m/s respectivly. Assuming a flat channel, determine a) the energy loss due to the jump, hl (head loss)
The saturated unit weight of the clay is 20kN/m 3 and that of the sand 19 kN/m 3 ; above the water table the unit weight of the sand is 16.5 kN/m 3 . Calculate the effective vertical stresses at the top and bottom of the clay layer.
The sample is placed in a 103 F oven overnight and is weighted again the next day. If the weight after drying is 0.85 lb and the specific gravity of the soil granuals is 2.65, what is the porosity of the soil sample
Air pollution in a city is caused by the following four sources: vehicle exhaust (V), industrial exhaust (I), dust (D), and pollen from plants and trees (T). On a particular day, the likelihood of air pollution caused by these sources is 4:3:2:1, ..
The circular top of a can has a radius of .0320m. the pull-tab has an area of 3.8x10^-4 m^2. The absolute pressure of the carbon dioxide in the can is 1.40x10^5Pa. find the force that these gas generates on the top of a can?
If a logit model is estimated with coefficients of -0.543 for distance and 0.0165 for commercial space (in 1000 of ft^2), how many shopping trips will be made to each of the four shopping centers?
The maximum gage pressure is known to be 8MPa in a spherical steel pressure vessel having a 250mm diameter and a 6mm wall thickness. Knowing that the ultimate stress in the steel used is (sigma u)= 400MPa, determine the factor of safety with respe..
Working a problem where there are two one-story buildings of different heights next to each other. Earthquake imparts a base motion z(t) that is a cosine function. I'm given a shape function for a column of height L when deriving the EOM for each ..
explain in your words the procedure of the Gauss-Newton method used to control some parameter (z) to meet some expected performance (y) using controllable parameters (A,B)
A concrete box girder bridge has the rectangular x-section. The box is prismatic and considered thin-walled. It span is L=48m and simply supported at points A,B,C and D. The supports are assume to be able to transfer tensile forces.
The emission rate of radon into the crawl space is reported to be 0.6 pCi/m^2-s. An exhaust system was added to provide 1 air exchange per hour (ACH) in the crawl space. The outdoor concentration of radon is 1 pCi/L.
The design of a masonry wall to support vertical compression loading is influenced by the same factors that affect the design of all compression elements. One of these factors is the extent of rotational restraint at the top of the wall.
