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.
Roller coasters are designed so that the riders will not experience more than a certain level of g-force during the ride. (The rider would experience B g's if hte normal force were Bmg where B is a numbe
Assume that you borrow $10,000 for five years (annual payments) at a market rate of 5%. Assuming that inflation is 3.5%, what would the equivalent equal monthly payment be in constant dollars

A hydraulic jump occurs in an rectangular channel 2.3 m wide when the discharge is 2.5 m^3/s. If the upstream depth is 0.25 m calculate the depth downstream of the jump and the energy loss in the jump.
The sulfur dioxide (SO2) stack-gas concentration from fossi-fuel combustion is 2 ppmv. Determine the stack-gas SO2 concentration in units of micro grams/m^3. Assume 0C and 1 atm pressure
a brass ring of 120-mm outside diameter is fits exactly inside a steel ring of 120-mm inside diameter when the temperature of both rings is 5 degrees C. knowing that the temperature of the rings is then raised to 55 degrees C
a saturated silty clay encountered in a deep excavation is found to have a water content of 23.5%. determine its porosity and bulk unit weight.
In the field, if the relative compaction is 90%, determine the hydraulic conductivity of the sand in the field compaction condition (given that k for the sand at the maximum dry density condition is .040 cm/sec and Gs = 2.65).
Compare the total reactor volume required for 90% removal of a substance that decays according to first-order kinetics with a rate constant of 0.05 day -1 in a CM system that contains a single reactor against a system that contains three CM reacto..
