A new bridge is to be constructed over the East River in New York City. Two structural possibilities exist: the support could be in the shape of a parabola or the support could be in the shape of a semi-ellipse.

The space between the supports needs to be 1050 feet.

The height at the center of the arch needs to be 350 feet. Determine the equation of a parabola with these characteristics. (Hint: Place the vertex of the parabola at the origin to simplify calculations).

Part 1

a. What is your equation for the parabola? An empty tanker, 520 feet wide and 260 feet high needs to pass beneath the bridge.

b. Can the tanker pass under this bridge? Justify your answer. Determine the equation of a semi-ellipse with the same characteristics. (Hint: Place the center of the semi-ellipse at the origin to simplify calculations)

Part 2

a. What is the equation for the semi-ellipse? Show the work required to determine the equation.

b. Will the tanker (520 feet wide and 260 feet high) be able to pass under this bridge? Justify your answer.

Part 3

a. If the river were to flood and rise 10 feet, how would the channel widths and the clearances of the two bridges be affected? Explain, using numbers, how the width of the channel would be affected for each bridge.

b. With all things considered, which bridge design would you choose? Explain your reasoning.

2. If the percentage end lap is 65%, what is the ground area (in sq. meters) of the end lap?
3. What was the air base?
4. If the aircraft flew and at a speed of 250 km/hr, what was the intervalometer setting?

A surveying team has to conduct a surveying assignment on a hot summer day. The area where the survey is supposed to be conducted is in the vicinity of a busy metropolitan area with lots of traffic. Assume the surveying firm has the following tools: gunter’s chain, steel tape, EDM, Electronic theodolite and a total station. Which one of the instruments would be most suitable and what advantages does it have over other tools? Explain in terms of time, error in collection of measurements, accuracy, data collection and ease in the collection of data.

The state government maps have to be updated every 5 years or 10 years. This year (2020), a surveying agency was given the task of updating the Texas state map.
