The elevation of point M is 875.4. A transit was set at point M and a leveling rod was held vertically at point N. The horizontal cross line of the telescope was inclined so the reading of the horizontal cross line on the rod was 12 ft. The horizontal distance between the points is 250 ft. If the instrument is 5.25 ft above point M and the reading of the vertical limb is 2°, what is the elevation of N.
Plot a graph showing the discarge per unit width per unit width q for various depths if the specific energy remains constant at this value. What will be the depth when the discharge is 1/3 of the discharge at critical depth
A stainless steel tube with an outside diameter of 65 mm and a wall thickness of 5 mm is used as a compression member. If the axial normal stress in the member must be limited to 180 MPa, determine the maximum load P that the member can support.
Determine the unfactored dead load and live load on a typical interior roof beam, sketch the loading on the beam, and draw the shear and moment diagrams for the beam assuming the beam is simply-supported.
The service live load is three times the dead load. The 4-in leg contains a single line of 7/8 inch diameter bolts, and the 6 inch leg contains a double gage line of 7/8 inch diameter bolts.
Why is it necessary to require such conditions-sand cement ratio, w/c ratio and type of sand. A graded sand is specified for use in the mortar cube test. What would be the likely results if a one-sized sand was used instead of a graded sand.
A steel bar of length 30 inches and circular cross section whose diameter varies linearly from 0.50 inches at one end to 0.75 inches at the other is subjected to an axial tensile force of 4.5 kip. Find the change in length of the bar.
On a specific westbound section opf highway, studies show that the speed density relationship is u=uf *[1-(k/kj)^3.5]. It is known that the capacity is 4200hehicle/hr and the jam density is 210 veh/mile.
he base-10 logs of the annual peak discharges in cfs for WY 1965-2010 have a mean of 3.678 and a standard deviation of 0.456. Assume that the probability distribution of the annual peak discharges is log-normal
What is the maximum population that can be served by a 900 mm diameter main sewer constructed on minimum grade. If sewage flow in the pipe never exceeds a depth of 600 mm, estimate the actual population contributing flow to the main.
A dry detention basin is to be designed for a 70 ha residential development. The runoff coefficient for the area is 0.3 and the average rainfall during the year is 4 cm. What is the necessary volume for the basin
A water tank has a height of 120m, and its area of cross-section is 2000m. Water is released from the tank and the water level drops by 1 meter every minute. Find the rate of change in volume.
A steel bar is attached to a wood support beam with four 20 mm diameter lag screws. The steel bar is 75-mm-wide by 6-mm-thick. For the steel bar, the yield strength is 260 MPa and the ultimate bearing strength is 350 MPa.
