1.The speed limit for a highway is given as "V" in mph. Thehighway super elevation is given as "e" in ft/ft. The frictionbetween tires and wet pavement is given as "f".
Develop an equation for a safe minimum design radius "R" for ahighway horizontal curve in terms of V, e, and f.
2.Write a paragraph explaining how the relaxation modulus of a plastic material measured in engineering practice. use a sketch.
A rectangular concrete beam of width b = 24 inches is limited by architectual considerations to a maximum total depth of h = 16 inches. it must carry a total factored load moment of Mu = 400 ft-kips.
Calculate the undrained shear strength at a depth of 120 ft below the mudline. Calculate the undrained shear strength at a depth of 120 ft below the mudline if the soil has an OCR of 2.5 .
an electrical-generation utility sometimes pump liquid water into an elevated reservoir during periods of low electrical consumption. this water is used to generate electricity during periods when the demand for electricity exceeds the utilities a..
Water with a static pressure of 1.96kN/M2 flows through an 800 mm diameter pipe. A pitot tube pressure gage in this pipe reads a pressure of 5.88 kN/M2. Determine the velocity (V)

An equal tangent vertical curve conects an initial grade of -3% and a final grade of +1% and is designed for 60mi/h. The PVI is at station 250+50 and elevation 732 ft. What is the station and elevation of the lowest point on the curve
A water column in a glass tube is used to measure the pressure in a glass pipe. The tube is 1/4 in. in diameter how much of the water column is due to the surface tention effects
A cylindrical metal specimen 12.0 mm in diameter and 120 mm long is to be subjected to a tensile stress of 40 MPa . at this stress level the resulting deformation is totally elastic.
Box I contains 3 red and 5 white balls, while Box II contains 4 red and 2 white balls. A ball is chosen at random from the first box and placed in the second box without observing it's color. Then a ball is drawn from the second box.
A solution of HOCl is prepared in water by adding 15 mg HOCl to a volumetric flask, and adding water to the 1.0 L mark. The final pH is measured to be 7.0. What are the concentrations of HOCl and OCl
given s=.30/(60-u), where s is the spacing (space headway) in miles, and u is the speed in miles per hour, derive the relationships u-k, u-q, and q-k. Also, estmate the capacity (qmax) of the roadway.
