A six-lane freeway (three lanes in each direction) operates at capacity during peak hour. It has 11-ft

lanes, 4-ft right shoulders, and there are three ramps within three miles upstream of the segment

midpoint and four ramps within three miles downstream of the segment midpoint. The freeway has an

AADT of 60,000 veh/day. The traffic stream has 8% heavy vehicles, and it is on rolling terrain with a

peak- hour factor of 0.85. It is known that 12% of the AADT occurs in the peak hour and that the

directional factor is 0.6. What is the freeway’s LOS?

The Challenger disaster was caused in part by a lack of awareness of how a particular environmental condition affects viscoelastic behavior. What was that condition? What type of material was affected in this case? How do you think this disaster probably influenced public perception of engineering responsibility in terms of global, economic, environmental impacts?

If point A has f=23.00N and l=58.00E and the distance between A and B = 700 km and azimuth from A to B = 211°. By iteration find the latitude f and longitude l of point B, Note: Find WGS84 ellipsoid a = 6378.137 km and b = 6356.752 km If point A has f=23.00N and l=58.00E and the distance between A and B = 700 km and azimuth from A to B = 211°. By iteration find the latitude f and longitude l of point B, Note: WGS84 ellipsoid a = 6378.137 km and b = 6356.752 km

A processing plant is producing minced meat, which must contain 15% of fat. If this is to be made up from boneless cow beef trimmings with 25% of fat, 10% protein, 64% water, 1% minerals and from boneless bull beef with 5% of fat, 20% protein, 72% water, 1% mineral. What are the proportions for these to be mixed? Report the ratio of boneless cow beef trimmings to boneless bull beef (e.g., 2:1) Assume the minced meat with 15% fat is to be smoked and then dried to produce beef jerky. Beef jerky requires a water to protein ratio of 1:1. How much jerky will be produced if one starts with 2,000 lbs of 15% fat minced meat?

Critically examine a floor/slab and state precisely what might be the causes of water lodging in corridors due to driving rain.

1. (A) Describe how fatigue damage happens in a ductile material. Draw sketches if needed. (B) If we maintain a constant stress σ = 0.9σy (σy is the yield strength) on a steel, will fatigue damage happen? Why?

1. The figure below shows a square foundation which applies a load of 63 kN/m2 at the ground surface. The soil profile consists of 3 clay layers where the coefficient of volume compressibility for the clay falls linearly from 0.05 m2/MN at the ground surface to 0.025 m2/MN at the bottom of layer 3. The stress change distribution with depth due to the foundation load is shown in the table.

a) Calculate the total consolidation settlement at the centre of the foundation above?

b) A similar foundation was constructed on a different site where 7m of sand overlies 7m of clay over a bed of impervious rock. The coefficient of consolidation for the clay is 0.7 m2/year and the coefficient of volume compressibility 0.05 m2/MN. In Oedometer tests on a 19 mm thick sample of clay from the site, 90% consolidation was reached at 76 minutes. How long would it take the clay to reach the same degree of consolidation on site?

c) Calculate the permeability of the clay in part (b).
