1) An equal-tangent crest vertical curve has a 50 mi/h design speed. The initial grade is +3%. The high point is at station 33+37.43 and the PVT is at station 37+18.26. What is the elevation difference between the high point and the PVT?
2) A 1400-ft-long sag vertical curve (equal tangent) has a PVC at stateion 115+00 and elevation 750ft. The intial grade is -3.5% and the final grade is +6.5%. Determine the elevation and stationing of the low point, PVI, and PVT.
Assume the beam is 2" x 10" in cross section. Calculate the bending stress distribution that is present at the base of the cantilever and at every 2.5 ft increment toward the free end of the beam
A dye test reveals that the specific discharge between the two wells is about 2.75 m/day. if the wells are 45m apart, What type of aquifer material do you expect in this location
The dry weight of a core is 28.20 gm. When saturated with a brine having a density of 1.15 gm/cc, the weight increases to 31.50 gm. Calculate the apparent porosities if the matrix is 1) quartz or 2) calcite.
The elevation of the lowest bottom of the structure is at 1470 feet. Calculate the maximum length (feet) of the parabolic curve required to meet the given conditions.
The pollutant has a reaction rate coeeficient k of 0.25/day. Assuming is pollutant is well mixed in the lake, find the steady-state concentration of pollutant in the lake.
What are the different dimensionless groups that describe a golf ball. A golf ball has two velocities, a spin velocity and a forward velocity.
