1.A foot ball field(120x180) yards measures 1.08x0.72 inches on a photo. what is the scale of the photo? what would the field measure on the photo(in inches) if the field were on a plateau 600 feet above the general ground elevation.
2.A natural channel that is clean and irregular(n= 0.040) has a bottom width of 15 ft m, side slopes of 6:1 (H:V) and a bottom slope of 0.0002. Using Manning's equation, determine the normal depth in the channel for a discharge of 720 cfs.
3.If you have 10 kips acting downward on a foundation and footing, 4 feet long, with uniformly distributed load acting up ward of 2.5 k/ft (soil) also 4 ft long. what are the reactions, shear forces, and bending moments at the tree critical points?
the motion of a particle is defined by the relation x= 1.5t^4-30x^2+5t+10. where x and t are expressed in meters and seconds, respectively. Determine the position, the velocity and the acceleration of the particle when t=4s
For arectangular section (b(width) x h(thickness) that is subjected to aforce P that is applied at an eccentricity (e) measured from thecenter of area of the rectangle in the h (thickness) direction.
uniform rod makes with the vertical during the roll, and (b) the speed of the roller after it moves 4 ft., starting from rest. The roller rolls without slipping, and the rod hangs vertically (theta = 0) when the system is at rest.
From the results of an oedometer test on an undisturbed sample of clay taken at a depth of 10 m from the ground surface, the maximum vertical preconsolidation pressure (s’vmax or s’c) was found to be 560 kPa. The clay layer has a saturated unit weigh..
A flow of 0.1 cum/s flows down in a rectangular channel of width of 0.6m and having and adjustable bottom slope. If chezys constant C is 56, determine the bottom slope necessary for uniform flow with a depth of flow 0.3m. Also find the conveyance of ..
a cylinder has 500 cm3 of water. after a mass of 100 grams of sand is poured into the cylinder and all air bubbles are removoed by a vacuum pump, the water level rises to 537.5 cm3. Dteremine the specific gravity on the sand
Compute the magnitues of all the forces acting on member CDE of the frame. There are pins at C D and E and an 80 kelp force on the right. Length measurements are in ft.
Land is extremely valuable in this area therefore to win this job you need to consider innovative approach to reduce the waste areas
A well water has the following mineral contents in mg/L: Na+=20; K+=35; Ca+2 =15; Mg+2 =10; Sr=0.5; Cl- =40; HCO3- =65; CO3-2=5; SO4-2=15; and NO3=10.
Three-point bending test was performed on an aluminum oxide specimen having a circular cross section of radius 5.5 mm; the specimen fractured at a load of 850 N when the distance between the support points was 50 mm. Another test is to be performed o..
The distance from the point of intersection of the tangents to the PI of the second curve is 100m while the stationing of the PI of the first curve is 10+432.24.If the radius of the curveis 285.40 m,
A newly designed dam is to be modeled in the laboratory. The prime objective of the general model study is to determine the adequacy of the spillway design and to observe the water velocities, elevations, and pressures at critical points of the st..
