Canon 4 (act as faithful agents, avoiding conflicts of interest)
Which of the following contributed to the quick success of the revolution in Panama?
The cooperation of the Panama Railroad
T or F: Treaty negotiations between the U.S. and Columbia concerning the Panama Canal proceeded smoothly and without serious obstacles. However, the apparent success of the treaty negotiations was negated by the revolution in Panama.
Consider the function f(x) = x-2*sin(x). Find the location on the positive x-axis where f(x)=0. Note that x=0 is a trivial solution and is not the intended solution. Use the Newton-Raphson method. For this problem, a good first guess of the solution is important. Plot the function to obtain your first guess. An example spreadsheet is available on moodle. Your answer must contain at least 6 digits beyond the decimal point. Consider that the variable, x, is in radians and no conversion to degrees is re
Which of the following contributed to the failure of the floodwall and levee along the 17th Street Canal in New Orleans?
- The occurrence of a water-filled gap behind the floodwall shortened the soil's failure surface
- The soil strength was overestimated by the designers
T or F: At the time, the purchase of the French Canal Company by the U.S. was the largest real estate transaction in history.
Which of the following were particular to the lifecycle of the stegomyia mosquito?
- it will only lay eggs in an artificial container of clean water
- it prefers human blood
- it will only lay eggs near a building occupied by people
Why was Colonel William Gorgas appointed to the U.S. Canal Commission?
He was regarded as one of the leading experts in tropical diseases
Use a spreadsheet to a numerically estimate the derivative of the following function: f(x) = x^3 - x^2
what is the difference between the estimated value and the true value of the derivative at x=1 for an interval size of 0.05?
T or F: The Liberty Ship Hull failures were caused by the combination of stress concentrations and fatigue.
According to Chapter 9 of Beyond Failure, which of the following is an important difference between steel and concrete?
Steel arrives at a construction site in its finished state, whereas concrete is manufactured to some extent on the job site.
Which two general principles often appear in construction materials and structural engineering?
- Structural systems often fail at connections
- Innovative materials used in new applications often have poorly understood properties or behaviors
T or F: From an engineering perspective, the Panama Canal was a complicated project. Among the challenges was a lack of space, negotiating property rights, preventing damage to existing buildings, and satisfying the demands of unionized labor.
In retrospect, what did John Stevens' see as his most valuable service to the Panama Canal Project?
His political role in lobbying for a lock canal
During the tenure of John Wallace as chief engineer, the great Bucyrus shovels were not able to operate efficiently. Why?
There was a shortage of trains to carry away the soil
Use a spreadsheet to numerically estimate the integral of the following function: f(x) = x^4 - x^3 +x^2
What is the difference between the estimated value and the true value of the integral at x = 1 for an interval size of 0.05?
Senator Marcus Hanna made a compelling case before the Senate in favor of a canal route through Panama. Which of the following were among his nine reasons that a Panamanian route was superior?
- the engineering community favored the Panamanian route
- Panama had better harbors
- fewer locks were required at Panama
Which of the following contributed to the failure of the hurricane protection system in New Orleans during Hurricane Katrina?
- the system was underdesigned
- many levees were not high enough
- there was a lack on stable funding
How did Bunau-Varilla deceptively convince the Panamanians to ratify the treaty he negotiated with a Secretary of State John Hay?

Which of the following was not included in the Hay Bunau-Varilla Treaty?
Colon and Panama City would be part of the canal zone
What were the contributors to the Johnstown Flood?
- The dam was lowered to accomodate a road along its crest
- A trestle bridge was built across the spillway
- The outfall pipes in the reservoir were removed
- did not contribute -- piping undermined the foundation of the dam
What caused the Big Dig Tunnel Collapse?
The use of an epoxy anchor adhesive with poor creep resistance
Chief engineer John Wallace was not successful because he failed to realize what his real job was. What was it?
Preparing excavation by developing plans and infrastructure
What was John Stevens' greatest conceptual contribution to the Panama Canal Project?
He saw the excavation as a railway freight problem
Which of the following were major problems with the Austin Dam?
- The concrete construction was of poor quality
- The foundation was not designed properly
Senator Marcus Hanna made a compelling case before the senate in favor of a canal route through Panama. Which of the following were among his nine reasons that a Panamanian route was superior to the Nicaraguan Route?
- The Nicaraguan route had more curvature
- The transit time through Nicaragua would be twice as long
- The Panamanian route was much shorter

Canon 3 - issuing only objective and truthful public statements
