A 1200 ft. equal tangent crest vertical curve is currently designed for 50 mph. A civil engineering student contends that 60 mph is safe in a van because of the higher drivers line of site. If all other design inputs are standard, what must the drivers eye height be in the van for the students claim to be valid?
A tape is calibrated and found to measure 100.04ft between the 0- and 100-ft marks. What measurements should be laid out to establish a horizontal distance of 682.25ft?
For the data given below, derive the 2-hr unit hydrograph for a watershed having a drainagearea of 216 km^2, assuming a constant baseflow of 20 m^3/s.
Describe the crystalline or atomic structure of the following minerals: 1) Brucite 2) Gibbsite 3) Bentonite 4) Illite
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.
In an unconfined aquifer having K = 30/m/day, two observation wells, 3km apart, have water levels of 50 and 40 m, respectively, above the base of the aquifer. Determine the rate of flow.
Find the minimum flow rate of air and the heat exchanger second-law efficiency.
Suppose 500 people are approched outside of a grocery store to answer some survey questions. If each person decides independently whether or not to participate, and each has a probability of 0.1 of participating
To remove a nail, a small block of wood is placed under a crowbar, and a horizontal force P is applied as shown. Knowing that the maximum vertical force needed to extract the nail is 2600 N and that the horizontal force P is not to exceed 290 N, d..
A pile resists the tension developed by three stay cables for a major tent (Membrane) Structure. Assuming no bending is desired in the pile (no resultant horizontal component), what is the magnitude of the force S if the angle \thetaS = 30 degrees
A concentrated downward force of 2000 lb. is located 6' from the left support, and a uniformly distributed load of 200 lbs./lin. ft. begins 6' to the right end of the member. What force must be applied at each connection to maintain equilibrium?
