Manual Calculation:
Apply the Highway Capacity Methodology and calculate the free flow speed, density and level of service for a rural freeway with the following characteristics: 1650 veh/hr per direction 2-lanes per direction 0.75 interchange / mile Rolling terrain 12-foot lanes Obstructions at 2 ft from median lane, 4 ft from outside lane 10% trucks, 6% RVs PHF = .91 Non-commuter drivers (fp = 0.9) 2. A four-lane urban freeway (two lanes in each direction) is located on rolling terrain and has 12-ft lanes, no lateral obstructions within 6 ft of the pavement edges, and an interchange every 2 miles. The traffic stream consists of cars, buses, and large trucks (no recreational vehicles). A weekday directional peak-hour volume of 1800 vehicles (familiar users) is observed, with 700 arriving in the most congested 15-min period. If a level of service no worse than C is desired, determine the maximum number of large trucks and buses that can be present in the peak-hour traffic stream.
This weir is to be replaced by an uncontracted horizontal weir that will maintain the same upstream depth. Determine the height of the weir if the discharge coefficient is based on the following equation: C = 1.78 * 0.22(H/p)
Using the Internet or any other available sources, define in your own words the meaning of “inertial reference frame” and “apparent force” associated with non-inertial reference frame. Give examples of apparent forces.
The post has a square cross-sectional area. If it is fixed supported at its base and a horizontal force is applied at its end as shown
A sheet of rubber is stretched out over a ring of radius 0.25 m. I pour liquid water at 20?C on it, as in Fig. P3.205, so that the rubber forms a half sphere (cup). Neglect the rubber mass and find the surface tension near the ring.
make an inline function g(x)= x+ cos(x^5). plot it using vectors x= -5:.1:5; and y= g(x);. what is wrong with this graph. find a way to make it look more like the graph of g(x) should turn in both plots.
The space truss shown is supported by a ball-and-socket joint at D and by short links at A and C. Determine the support reactions and the force in each member of the space truss.
Figure 13.18 shows proposed curb locations, together with offset stakes for the north-side curb. The straight section of curb begins at station 0 + 15 and ends at station 2 + 10. With the aid of a sketch, show how these two chainages were determin..
The simply supported shaft has a moment of inertia of 2 I for region BC and a moment of inertia I for regions AB and CD . Determine the maximum deflection of the shaft due to the load P .
.An air turbine is used with a generator to generate electricity. Air at the turbine inlet is at 700 kPa and 25 degree C. The turbine discharges air in to the atmosphere at a temperature of 11 degree C.Inlet and outlet air velocities are 100 m/s and ..
When is it advantageous to use an unequal-tangent vertical curve instead of an equal-tangent one?
A flow of 125,000 gallons per day enters a sedimentation basin which is 20 feet wide, 60 feet long and 12 feet deep. What is the minimum settling velocity of a particles that will be 100% removed by the basin
A sample of undisturbed soil has a dry weight of 10 lb and volumen of 1 ft^3. If the specific gravity of the soil solids is 2.65, determine the void ratio and the porosity.
