Question 1 of 10
1. Question
A canal to be lined with concrete is 227ft long, there is a 12% allowance for waste. What volume of concrete must be delivered? The height is 14ft.
Correct
Side slope length = 14 x 3/2 = 21.0 ft
length of slope = 25.24
Area of lining = [(2 x 25.24) + 9] 7/12 = 34.70 ft
lining volume = (34.70 x 227)/27 = 291.7 yd3
volume delivered = 291.7 yd3 x 1.12(waste) = 327 yd3Incorrect

Question 2 of 10
2. Question
Using the straightline distribution method of depreciation, a book value after 8 years is $75,000. the salvage value is $10,000. What is the expected lifetime value after 10 years?
Correct
= $75,000$10,000/10 = $75,000 (8)($6,500) = $23,000
Incorrect
= $75,000$10,000/10 = $75,000 (8)($6,500) = $23,000

Question 3 of 10
3. Question
The budgeted amount for a project is $4,000. each employee cost $50 each for 8 hours. if two workers are assigned, how much time will it take to almost complete the tasks?
Correct
Cost of both employees = 2($50/hr) = $100/hr
Days to complete the job = (8 hr/day) x ($100/hr) / $4,000 = 5Incorrect
Cost of both employees = 2($50/hr) = $100/hr
Days to complete the job = (8 hr/day) x ($100/hr) / $4,000 = 5 
Question 4 of 10
4. Question
A design requires a hydraulic ram with minimum capacity of 1,000 kN(Kilonewtons), The rams are available are rated are (2,000 Ib/ton). What is the minimum size raqm that can be used?
Correct
1,000 kN = 1,000 kN x 1 ton/ 8.896444kN = 112.4 tons
150 tons > 112.4 tonsIncorrect
1,000 kN = 1,000 kN x 1 ton/ 8.896444kN = 112.4 tons
150 tons > 112.4 tons 
Question 5 of 10
5. Question
Which statement about lateral earth pressure is true?
Correct
The lateral strain needed to fully mobilize the passive pressure of the soil is substantially greater than the lateral strain needed to fully mobilize the active pressure of the soil.
Incorrect
The lateral strain needed to fully mobilize the passive pressure of the soil is substantially greater than the lateral strain needed to fully mobilize the active pressure of the soil.

Question 6 of 10
6. Question
If a 20 ft. of fresh filling is needed, has a mean consolidation settlement of 22 in. Affecting a region of 21.5 acres. $0.25 per gallon is charged to dispose of water due to contamination from the previous site use. What would be the cost for treatment and disposal for this project?
Correct
Affected area = 21.5 acres x 43,560 ft2/acre = 936,540 ft2
Mean consolidation settlement over affected area = 22 in. = 1.83 ft
Settlement volume = effluent volume = 936,540 ft2 x 1.83 = 1,713,868 ft3
convert to gallons = 1,713,868 ft3 x 7.48 gal/ft3
Cost of effluent treatment and disposal = 12,819,733 gal x $0.25/gal = $3,204,934Incorrect

Question 7 of 10
7. Question
To build a bridge footing in sand, the level of groundwater is at the surface of the ground. What type of soil unit weight will be the ultimate bearing capacity dependent on?
Correct
When building a bridge footing in sand and the groundwater is at the level of the ground, the ultimate capacity weight will depend on the buoyant unit weight.
Incorrect
When building a bridge footing in sand and the groundwater is at the level of the ground, the ultimate capacity weight will depend on the buoyant unit weight.

Question 8 of 10
8. Question
For permanent slopes under longterm nonseismic conditions affecting occupied structures, the minimum protection factor against rotational failure is closest to:
Correct
1.5 is the minimum protection factor for permanent slopes. The other comparison use of a safety factor greater than or equal to 1.3 is the nearest, but the choices offered are 1.5.
Incorrect
1.5 is the minimum protection factor for permanent slopes. The other comparison use of a safety factor greater than or equal to 1.3 is the nearest, but the choices offered are 1.5.

Question 9 of 10
9. Question
Consider two identical crosssection beams, made of the same material, having the same conditions of support, and each loaded at the same uniform load per length. One beam is twice the length of the other one. In the longer beam, the maximal bending stress is greater by a factor of:
Correct
In the longer beam, the overall bending stress is four times greater.
Incorrect
In the longer beam, the overall bending stress is four times greater.

Question 10 of 10
10. Question
The point load (kips) of a 30ft beam mounted at the centerline creates the same maximum shear in the beam as a uniform load of 1 kip/ft. The nearest thing is:
Correct
Uniform load: wL/2 = 1 (30)/2 = 3= kips/2 = 15 kips
Point load: V = P/2 = 15 kips
P = 2 (15) = 30 kipsIncorrect
Uniform load: wL/2 = 1 (30)/2 = 3= kips/2 = 15 kips
Point load: V = P/2 = 15 kips
P = 2 (15) = 30 kips
