Indicate True (T) or False (F):

a. The 4-step network level transportation planning approach is suitable to estimate travel demand along a corridor.

b. Traffic assignment does not refer to the estimation of zonal trip productions and attractions.

c. A logit model is not used to estimate modal utilities.

d. Mobility does not represent the operational performance of a transportation system.

e. Maximization of consumer surplus does not represent the objective of maximization of benefit of public projects.

f. Ton-miles cannot be used as a measure of freight transportation demand.

g. A change in the level of service (or quality) of a transportation system cannot be represented by a shift in the supply curve.

h. Cross-sectional models can be used to model demand functions.

A precast square concrete pile 305x305 mm in cross section is driven into ground using a steam hammer. If HE = 40 kN-m, E = 0.85, WR = 35 kN, weight of pile cap = 3.0 kN, L = 25 m, n = 0.4, Ep = 21 x 106 kN/m2 , number of blows for the last 25.4 mm pile penetration is 7 blows, unit weight of concrete = 24 kN/m3 . Compute the allowable pile capacity using: (a) Modified ENR formula (FS=6) (b) Danish formula (FS =4) (c) Janbu’s formula (FS=3) (d) PCUBC formula (FS=3)

Aerial photography can be used to produce a variety of map products useful for landscape management and engineering applications.

i. Briefly explain how a Digital Elevation Model (DEM) of a landscape can be generated from overlapping aerial photographs.

ii. What is an orthophoto? How does it differ from an aerial photograph?

iii. A potentially very useful product that can be supplied to landscape managers and engineers is a ‘stereo-model’ that can be viewed, interpreted, and measured using heads-up 3-dimensional viewing technology:

a. Explain how two images can be displayed on a computer screen and visualised in 3-dimensions?

b. What advantages might this technology offer a practising land manager or engineer?

What diameter of cast iron pipe would be required to ensure that a discharge of 0.2 m3/s would not cause a head loss in excess of 0.01 m/100 m of pipe length, assume water temperature is 20 oC

Write a one page on design philosophy for concrete buildings for gravity and lateral loads. Why are they important to be designed correctly?

A subbasin in Mississippi has a predominant urban land use (high density development) under soils with a hydrologic soil group D and a potential abstraction of 0.53-in. Analyses of flow data indicate that for a 6-hr runoff event the flow of the unit hydrograph linearly increased to reach a peak of 9.6 ft3/s in 8 hours. As well, the time that takes runoff to travel from headwaters to outlet is 12-hr. Considering the recession phase of the hydrograph in also linear, determine the subbasin area (acres).

Q1: Design L2L3 member as shown below using double-angle section with 3/8-in gusset plate between the angles. Assume two-lines of three ¾-in bolts in each vertical angle-leg, spaced at 4-in on center. Use A36 steel. ​

Q2: Draw (sketch) the connections at L2 and L3 assuming all truss members are designed using double angle sections, and using the same amount of bolts.

PD= 60 kips, PL=48 kips​

A car is traveling at 20 mi/h on a roadway covered with hard-packed snow (coefficient of road adhesion of 0.25). The car has CD = 0.30, A_f = 22 ft², and W = 2800 lb. The wheelbase is 120 inches, and the center of gravity is 20 inches above the roadway surface and 50 inches behind the front axle. The air density is 0.002045 slugs/ft³. The car’s engine is producing 100 ft-lb of torque and is in a gear that gives an overall gear reduction ratio of 4.5 to 1, the wheel radius is 14 inches, and the mechanical efficiency of the drivetrain is 80%. If the driver needs to accelerate quickly to avoid an accident, what would the acceleration be if the car is front-wheel drive

a. 3.78 ft/s^2

b. 3.83 ft/s^2

c. 2.83 ft/s^2

d. 2.78 ft/s^2
