Question 1 of 10
1. Question
If the PI station is 12+40.00, the degree of the curve is 10° and the deflection angle is 12°30′. What is the station of the PT?
Correct
R = 5,729.648/D°c = 5,729.648/10 = 572.96 ft
T = R tan (1/2▲) = R tan (6.25°) = 572.96 (tan 6.25°) = 572.96 (0.1095178) = 62.75 ft
Station PC = Station PI – T =[12+40] – 62.75 = 11+77.25
Station PT = Station PC + length of curve
Length of curve = L = 100 ▲/D°c = 100(12.5)/10 = 125 ft
Station PT = Station PC + 125 ft = (11+77.25) + 125 = 13 + 02.25Incorrect
R = 5,729.648/D°c = 5,729.648/10 = 572.96 ft
T = R tan (1/2▲) = R tan (6.25°) = 572.96 (tan 6.25°) = 572.96 (0.1095178) = 62.75 ft
Station PC = Station PI – T =[12+40] – 62.75 = 11+77.25
Station PT = Station PC + length of curve
Length of curve = L = 100 ▲/D°c = 100(12.5)/10 = 125 ft
Station PT = Station PC + 125 ft = (11+77.25) + 125 = 13 + 02.25 -
Question 2 of 10
2. Question
Traffic count data for a day in the month of January to December are 63,500, 62,100, 64,400, 64,900, 75,800, 77,300, 78,950, 77,200, 70,050, 69,000, 66,000, 64,000 respectively. What is the seasonal factor for the months of June through August?
Correct
AADT = 63,500 + 62,100 + 64,400 + 64,900 + 75,800 + 77,300 + 78,950 + 77,200 + 70,050 + 69,000 + 66,000 + 64,000/ 12 = 69,433
June through August = 7,300 + 78,950 + 77,200/3 = 77,817/69,433 = 1.121Incorrect
AADT = 63,500 + 62,100 + 64,400 + 64,900 + 75,800 + 77,300 + 78,950 + 77,200 + 70,050 + 69,000 + 66,000 + 64,000/ 12 = 69,433
June through August = 7,300 + 78,950 + 77,200/3 = 77,817/69,433 = 1.121 -
Question 3 of 10
3. Question
Three samples are 6 inches in diameter and 12 inches in height and they are tested to confirm the strength of the concrete.The results are 65,447, 63,617 and 79,168 respectively. what is the average 28-day compressive strength?
Correct
Area = πd²/4 = 28 in²
Compressive stress = axial load/are
Sample 1 = f’c = 65,447/28 = 2,313 psi
Sample 2 = f’c = 63,617/28 = 2,248 psi
Sample 3 = f’c = 79,168/28 = 2,797 psi
Average = 2,313 + 2,248 + 2,797/3 = 2,452 psiIncorrect
Area = πd²/4 = 28 in²

Average = 2,313 + 2,248 + 2,797/3 = 2,452 psi -
Question 4 of 10
4. Question
If the combined weight of soil and mold is 9.11 lb, water content is 11.5%, weight is 4.41 lb, and volume of mold is 0.03 ft³. What is the dry unit weight of the soil?
Correct
Total density (Y) = W/V = (Ws+Ww)/(Vs+Vw+Va)
Y is total density, W is the total weight, V is total volume, Ws is wight soil, Ww is the weight of water, Vs is the volume of soil, Vw is volume of water, and Va is the volume of air.Y = 9.11 lb – 4.41 lb/ 0.03 ft³ = 156.67 lb/ft³
Dry unit of weight soil (Yd) = Y/(1 + w)
Where w is moisture contentYd = 156.67/(1 + 0.115) = 140.51
Incorrect
Total density (Y) = W/V = (Ws+Ww)/(Vs+Vw+Va)
Y is total density, W is the total weight, V is total volume, Ws is wight soil, Ww is the weight of water, Vs is the volume of soil, Vw is volume of water, and Va is the volume of air.Y = 9.11 lb – 4.41 lb/ 0.03 ft³ = 156.67 lb/ft³
Dry unit of weight soil (Yd) = Y/(1 + w)
Where w is moisture contentYd = 156.67/(1 + 0.115) = 140.51

5. Question
A storage facility is 100 ft x 100 ft, has a 200 psf floor live load, a flat roof that accommodates 50 psf snow load, and a building weight of 200,000 lb. What is the minimum lateral force for the entire building?
Correct
F = 0.01 w w= dead load = 0.01 (200,000) = 2,000 lb
Incorrect
F = 0.01 w w= dead load = 0.01 (200,000) = 2,000 lb

6. Question
what is the maximum service carried by a beam of 30 ft if moving load is applied to it?
Correct
M = PI/4 = (20 kips)(30 ft)/4 = 150 ft-kips
Incorrect
M = PI/4 = (20 kips)(30 ft)/4 = 150 ft-kips
