1.Write the term paper on Relationship Between Speed and Safety in Geometric Design of Highways.
2.A light spring of a constant k=90.0 N/m is attached vertically to atable. A 2.00g balloon is filled with helium (density 0.180 kg/m^3)to a volume of 5.00m^3 and is then connected to the spring, causingit to stretch. Determine the extension distance L when the balloonis in equilibrium.
A curved section of a two-lane highway measured in the field was found to be 22 feet wide and have an elevation difference of 1.37 feet between the outside and inside edges of the pavement
if the rolling resistance is 1/100 of the weight of the car, determine the compression of each spring when the car is momentarily brought to rest spring 1 500kN/m spring 2 300kN/m and distance between springs and car 30m

The propellor is situated at the end of the tunnel wherethe area is 10 m2 (rigth before the tunnelis opened to the atmosphere). So I used the energyequation, but I have two unknows: pressure P of thetest section, and the shaft work hT orhP (I am not ..
Theis Method plot drawdown vs. time for 4 observation wells, 5, 50, 100, 500 meters from well pumping at constant rate of 300 m^3/day in sandy confined aquifer. b=12 m, K=25 m/day, and S=10^-4.
IF the bulk density of coarse grained soil is 1760 kg/m^3 what is its void ratio, e, and saturation, S. Draw the complete phase body diagram and show the masses and volumes.
The mine wants to change the hole diameter to 229 mm and needs a new drilling pattern that will not result in coarser fragmentation. For this exercise you can assume homogenous geology and no adverse effects due to geological structure.
An open rectangular channel is 50 feet wide, flowing at a depth of 5 feet, and is carrying 1000 cubic feet per second. What is the maximum step height than can be placed into the flow without disturbing the upstream depth, without acting as a chok..
The torsional assembly consists of a solid bronze [G = 49 GPa] segment (1) with diameter d1 = 90 mm securely connected at flange B to solid stainless steel [G = 89 GPa] segments (2) and (3), with diameter d = 100 mm.
What will the freeway's density and level of service be before and after the ban? (Assume that the trucks are removed and all other traffic attributes are unchanged).
It's proposed to have a water heater that consists of an insulated pipe of 5-cm diameter and an electric resistor inside. Cold water at 20oC enters the heating section steadily at a rate of 30L/min.
A body consists of a right circular cone whose base is 12 in. and whose altitude is 16 in. A hole 8 in. in diameter and 4 in. deep has been drilled from the base. The axis of the hole coincides with the axis of the cone. Locate the centroid of the..
