A pre-engineering baseline was run down a very steep hill. Rather than measure horizontally downhill with the steel tape, the surveyor measures the vertical angle with a theodolite and the slope distance with a 200-ft steel tape. The vertical angle is -2126' turned to a point on a plumbed range pole that is 4.88 ft above the ground. The slope distance from the theodolite to the point on the range pole is 148.61 ft. The theodolite's optical center is 4.66 ft above the upper baseline station at 110+71.25.
a) What is the stationing chainage of the lower station?
b) If the elevation of the upper station is 318.71, what is the elevation of the lower station corrected for both, curvature and refraction?
Soil is excavated from a borrow to construct an embankment with a net volume of 50,000 cy with 95% of Modified Proctor maximum dry density of 110 pcf with a Modified Proctor optimum water content of 8%.
If the temperature of the flashlight increases to 120oF, does the spring force increase or decrease and by how much. Take the casing wall to have an outer diameter of 1.5 in., thickness 0.125in.,length L = 3 in., and elastic modulus of 300ksi.
There are many parallels between the industrialization of the United States after Reconstruction and the modernization of the American workforce in the last twenty to thirty (20-30) years as it transitions from industry to a service-oriented econo..
A well-mixed sewage lagoon (a shallow pond) is receiving 430 m^3/d of sewage out of a sewer pipe. The lagoon has a surface area of 10 ha (hectares) and a depth of 1 m. The pollutant concentration in the raw sewage discharging into the lagoon is 18..
A telephone wire 5 mm in diameter is suspended between telephone poles spaced 50 m apart. If the wind velocity is 100 km/h and the air is at 2 degrees C, 1 atm, determine the horizontal force (in N) the wire exerts on the poles.
A steel bolt and nut are tightened around an aluminum sleeve. Find the internal forces as the nut is rotated 1 turn
What is the reaction that occurs with hexanal and propanol (give both the hemiacetal and acetal products)?
An element of aluminium in a form of a rectangular parallel pipe has a length 'a' along the x axis of 5.5 in, a length 'b' on the y axis of 4.5 in. Determine the maximum shear stress in the material,the change in length.
1.How long is the irrigation boom (in feet) from the center pivot to its farthest extent. 2.If the irrigation boom makes 4 full revolutions in a day, how many miles does the end of the boom travel in 4 days.
An agricultural waste lagoon has a total volume of 500 m^3 and has an initial dissolved oxygen (DO) level at the saturation for 20 °C. This waste lagoon receives a discharge of 1,750 L of runoff containing an ammonium loading of 500 mg as N per li..
Assuming Stokes behavior, calculate the terminal settling velocity in standard air for the following particles: (a). diameter = 10 micrometers, specific gravity =1.2; and (b) diameter = 4 micrometers, specific gravity = 2.0.
