A zenith angle was measured six times with both faces of a total station. The average direct
reading is 86°34′31″ with a standard deviation of ±12.8″. With the reverse face, it was
observed as 273°25′12″ with a standard deviation of ±8.8″. What is the most probable value
for the zenith angle in the direct face?

Superstructure Frames: Construction

Using all the different "design types" of superstructure frames (Concrete frame, Timber Frame, Steel Frame), how would you "design/build" a high-rise in your area (California, Fresno), and what types of structural systems would you use? You may make geographical assumptions to fit your model building.

According to superfund (CERCLA), what is the formal steps to follow in the cleanup process? How much is the current EPA budget for the Superfund program? How the regulations are applied for recouping cleanup costs?

What are the three forms of communications for engineers?

Explain the importance of data collection and information research on a project outcome.

Define the Professional Responsibility of Practicing Engineers toward the public, the employer and the environment.

A retaining wall with sloping back, of vertical height 9m retains soil of density 1.6 Mg/m³, and angle of friction 30^o. The soil slopes upwards at 20^o to the horizontal from the back edge of the wall, the angle between the slope and the back of the wall is 100^o. Cohesion 10kN/m², angle of friction between soil and wall is 25^o but there is no cohesion between them. Find the thrust on the back wall per metre run using trial values of 25, 30, 40, and 45^o for the inclination for the plane of rupture to the vertical.

General Manager at the Council is considering awarding your team to a new project in Altona North.
The General Manager has invited you to submit a report describing some key items relating to how you
would manage the construction activities. Your report needs to include at least the requirements
below.

a)project monitoring and control

b)project quality

c)project safety

Why is the applicability of statistical quality control (SQC) an important attribute of an MTS operation? Why is it not applicable to an MTO operation?

. The average flow of wastewater into the Metropolitan Wastewater Treatment Plant is 180 MGD. What is the loading of total solids in this wastewater (lbs/day)? What is the loading of volatile solids in this wastewater (lbs/day)?

Use the Hazen-Williams equation and the Manning equation to calculate the flow rate for problem 3.5.7 which was solved using the Darcy-Weisbach equation and yielded Q = 78.8 m^3/sec. Compare the results and discuss the differences. Assume minor losses are negligible and verify your results with computer software.

You are driving along straight road. You cover 200 miles in 4 hours? Does that mean that your speedometer read 50 mph for your entire trip? Is is necessary that your speedometer register 50 mph at least once during the trip? Use math to explain your answer.

I understand that your speedometer would not be 50mph for the entire trip, but I am not sure how to explain it using math.

´The velocity of oil flowing thru a 30 mm diameter pipe is equal to 2m/s. Oil has a kinematic viscosity of 5 x 10 -5 sq.m/s. If the pipe has a length of 120 m, compute the Reynolds Number, friction factor, and head loss in the pipe.
