Consider the challenges of exposure and environmental conditions.2) What legal, economic, environmental, and societal issues can be linked with building structures in Antarctica?

capacity of a 1-km section of northbound Highway 3 located on a 3.5% upgrade. The highway has three 3.5m-wide lanes in one direction with no lateral obstruction within 5m of the pavement edges. The ideal (base) free-flow speed is 100 km/hour. You observed that percentages of cars and truck are 90% and 10%, respectively (no RVs). A weekday peak hour volume is 4320 vehicles, with 1200 vehicles arriving in the most congested 15-minute period. Since a majority of drivers are local commuters and truck drivers, you assume that they are generally familiar with the highway. The interchange density is 0.75 interchange per km.
(a) Determine the level of service (LOS) for the highway. If the required LOS is “C”, is the current highway capacity enough to handle the traffic?
(b) If the number of lanes in one direction were increased to 4 lanes, would the LOS in part (a) be improved?

How did the Great Awakening inspire ordinary citizens to assert their right to independent judgement? Did the movement expand freedoms?

2. Describe the effect of geological structure on tunnel excavation by drawing three-dimensional figures.

Mohammed completed a self-paced carpentry skills program in record time and then went to work for a company that makes the custom kitchen and bathroom cabinets. He has been there long enough to know that kitchens and bathrooms will not be his life work. Instead, he will be opening his own business. “The Big Picture” will be a picture framing service that will sell framed posters and prints. As well, it will provide framing for the customer’s own pictures and re-finish old frames.

Mohammed has found a vacant store in a medium-sized suburban mall in a slightly upscale neighborhood. The store, as it currently stands, is a 25' x 40' rectangle with one end opening into the mall and a small door at the back that opens to the outside delivery area. The only fixture is a sink in one back corner.

Mohammed is negotiating with the mall owner who is willing to share the costs of the “leasehold improvements” that will be required to make the store suitable for The Big Picture. Already, Mohammed recognizes that the store will have to be divided into two distinct areas: a front sales area and a backroom work area. But the details are still to be worked out.

The sales and display area where customers can browse work ready for sale will have to contain a sales desk for the cash register and another work desk to show completed work to customers and inspect the work they bring in for repair or refinishing. There will also have to be an area to display the various choices in frames and mattes.

The work area will have to include a large 5' x 8' work table with various clamps. Space will be needed for a sanding machine as well as a bench with a vice for hand sanding. There will be a painted table and an area to hang drying frame parts that will need to be as far away from the sanding area as possible. An area around the sink will be needed for mixing stains and for clean-up. There will also have to be storage areas for pre-manufactured frames, for various wood moldings and for various sizes of wood stock. A storage area for paints and various finishes will also be required as well as a storage area for hand tools.
