Put in Order

Put in order the steps for cutting a coped joint. Write the corresponding numbers on the blanks.

A. Mark a W to indicate which side of the molding fits against the wall.

B. Carefully cut along the outlined profile with a fine-tooth coping saw blade, keeping the saw blade plumb.

C. Hold the molding so it is over the end of the sawhorse, and the side of the molding that will fit to the wall is flat on the top of the sawhorse.

D. Cut a molding piece to fit into the corner with a squared end and install.

E. Cut a miter on molding so it would fit into corner as an inside mitered joint. Rub a pencil along the edge.

1. In your own words, identify what the difference in volume is between effective precipitation and the volume under the hydrograph that is the response to that precipitation. Show how to calculate each. Use SketchAssist if useful; this is a mental App that everyone is born with.

A lined canal (n = 0.016) is designed to carry a flow rate of 33 m3/s. The canal is laid at a slope of 14 cm/km with a side slope of 2:1. Design the canal cross section (the water depth and bed width) according to each of the following scenario:

1. If Velocity is 1.0 m/s

2. If the Most efficient hydraulic section (i.e., when Rh=y/2)

3. If Width/depth =5

Comment on the practicality of the designs (Height of side slope, flow

velocity, variability of depth under reduced flows, land area for the canal).

Design an individual column footing where DL = 200k, LL = 500k, allowable soil pressure = 3k/ft2, f′c col = 4ksi, f′c ftg = 3ksi, 28″ x 28″ column, supporting interior column.

Design for flexure a simple span beam 26’ long to carry P_D = 1000# and P_L = 2000# at the center of the span. f’_c = 4,000psi and f_y = 60,000psi. show all work

Describe the tradeoffs to be assessed between using a "broadly" or a "narrowly" graded ballast.

You work for a general contractor experiencing increased rate of “high frequency, low impact” incidents. Specifically, the company has observed an increased rate of incidents associated with overexertion, slips trips, and falls at the same level, back pain, sprain and strains, and fatigue. You are asked to propose a solution to this problem. Your boss mentioned that they are open to implementing technologies or a combination of technology and effective safety practices. In about 300 to 500 words:  

• Describe how you would develop a safety program aimed at tackling this problem.
• Justify the selection of each item in your proposed program and provide information on the effectiveness of the program.
• Provide the approximate cost of implementing the items in the program, where available.
• Include a brief description of the strengths and potential weakness(es) of the program

Question 1:

A) Identify five promising technologies used for construction, safety and health management. For each technology, highlight at least three benefits and three limitations.

B) Using Hierarchy of Control framework as a guide, discuss the impact/effectiveness of technologies discussed in problem 1.

1. Primary sludge containing trickling filter sludge is gravity thickened in a circular tank with a diameter of 12 ft, and side water depth of 10.0 ft. The applied sludge is 2600 gpd with 4.5 % solids (by wt.) and the thickened sludge withdrawn is 1300 gpd at 7.5 % solids (by wt.). The sludge blanket in the tank is 3.0 ft deep. For odour control, and to enhance thickening, 45,000 gpd of treated wastewater is pumped to the tank along with the sludge to increase the overflow rate. Calculate the solids loading on the tank, the solids capture efficiency, the overflow rate, and the solids retention time in the tank, assuming that all the tank solids are in the sludge blanket.
2. If the thickened sludge from the tank that is anaerobically digested, at an SRT of 15 days with a VS destruction efficiency of 50%, calculate the size of the anaerobic digester, and the daily methane production rate. Assume that the volatile fraction of solids is 70%.

A grit chamber is designed to treat an average wastewater flow of 1 m³/sec at an overflow rate of 4752 m³/m² –d to capture sand with the following particle size distribution:

         % by wt.                        Diameter (mm)

               30                                         1.0

               30                                         0.5

               30                                         0.2

               10                                         0.1

The design overflow rate is such that 100% removal of the 0.5 mm diameter particles will be achieved. The operating temperature is 20°C and the specific gravity of the sand particles is 2.65. Assume that the stickiness coefficient (k) for sand is 0.04 and the Darcy-Weisbach friction factor (f) is 0.03.

a. Determine the surface area and vertical cross-sectional area of the grit chamber if only the 0.1 mm diameter particles will be scoured away

b. Calculate the removal efficiency assuming that only the 0.1 mm diameter particles will be

     scoured away.

c. If the ratio of peak to average flow is 1.4, calculate the overall removal efficiency at the      peak flow.
