Compare between Flexible Pavement Design using Asphalt Institute Methods and AASHTO Design method.

A precast T beam is to be used as a bridge over a small roadway. Concrete dimensions are b = 1500 mm, bw = 300 mm, hf = 150 mm, and h= 650 mm. The effective depth d= 500 mm. Concrete and steel strengths are f 'c= 40 MPa and fy = 420 MPa, respectively. Determine the design moment capacity of the girder. If the beam is used on a 10 m simple span, and if in addition to its own weight it must support railings, curbs, and suspended loads totaling 4 kN/m, what uniform service live load limit should be posted?

A lightweight rope is wrapped around a 100-lb
drum, passes over a frictionless pulley, and is
attached to a weight W (see figure). The
coefficient of friction between the drum and
the surfaces is 0.50. Determine the maximum
amount of weight that can be supported by
this arrangement.

Please answer the question as best you can without providing extraneous information. GIS (1) a) Describe the similarities and differences between joining tables and relating tables. b) Provide a specific example that illustrates when one can be used while the other cannot.

1. Share one personal experience (job or observation or from your readings) related to any one modern technology used to improve construction process. Is the technology widely used in the industry? If not, what do you think is the main obstacle in its wider application?
2. Do you agree that green buildings can produce savings for property owners and tenants alike? Please discuss by providing at least one example.

What is called Supertargetting in Heat Exchanger Network Design? How Heat Exchanger Network Design can be done by paying attention to Supertargetting?

Select double angle tension member to resist a factored load of 100 kips. Member is connected with 2 lines of 3⁄4-inch diameter bolts placed at usual gage distances (see AISC manual specification J3.3). There will be more than 2 bolts in each line. Member is 15’-0” long. Hint: Try an angle with 6 inch legs back to back and an outstanding length of 3 1⁄2 -inches. Choose required thickness. Assume U=0.85 for design.

Indicate 2 different rights in the Bill of Rights that the U.S. Supreme Court still has not incorporated and made applicable to the states through the Due Process Clause of the 14 th Amendment? Be specific and indicate the right AND the Amendment where that right is found in the Bill of Rights.

A new, wide highway embankment is planned across a relatively recent deposit of doubly-drained, saturated clay soil with cv = 5E-8 m2/sec. The settlement analysis of the 10 m thick clay layer yielded an estimated consolidation settlement of 800 mm for the new embankment loading. Determine and plot the settlement of the clay layer (as measured at the ground surface) at 0, 0.49, 3.12, 6.39, 13.44, and 18.44 years.

• Why did Eisenhower warn the American people to be cautious of the growing military-industrial complex? What concerned him?
• Do you perceive the relationship between the military and weapons/security industries to be a good thing for national security? Do you think it's a bad thing? Provide detailed reasoning for your answer.

Mining Engineering

At a open pit mine the bench height is 15m, the vertical blasthole diameter is 250mm and the rock has a specific gravity of 2.9. If ANFO with a density of 0.8g/cc is used with a square pattern where S = B, determine: 1. Burden 2. Spacing 3. Subdrill 4. Stemming length 5. Blasthole length 6. Charged length 7. Rock broken/blasthole 8. Powder factor

1. You are located downwind from two oil-burning power plants. One is located 0.3 km NE of your location and burns 1400 kg of 0.5% sulfur oil per hour. Its effective height is 60 m. The second plant is located 0.5 km NNW of you and burns 1600 kg/hr of fuel oil containing 0.75% sulfur. The effective height is 40 m. The wind is blowing from NNE at 3.3 m/s (measured at the standard height of 10 m). For a class B stability condition, what is the SO₂ concentration at your location at ground level?
