FS EXAM Fourth Edition Session 2 Exam Questions and
Answers
A 1000 ft long earthen berm has a cross section with an area of 1500 ft² at one end and
2000 ft² at the other end, with area increasing at a constant rate. What is the approximate
volume of material in the berm? - -V = l((A1 +A2)/2)
= (1000)((1500+2000)/2)
= 1,750,000 ft²
1,750,00 ft²/(27/1) = 64,815 yd³
-Which of the following is the best definition of mean sea level? - -The average of all the
water heights over a tidal epoch
-On a topographic map, which of the following is correct? - -Contour lines crossing
streams form V's that point upstream
-What is the effect on the location of a coastal boundary when natural and gradual changes
occur to the shoreline? - -The boundary changes with the changing shoreline
(accretion or erosion)
-Choose the correct option for the underlined words in the following sentence: "He
presented an explanation as to how temperature affects distance measurements and what
effect this has on the accuracy of the survey." - -No change is necessary
-What is the sum of matrices A and B?
A = [4 2] B=[1 5]
3 5 3 2 - -A = [ 4 2 ] B = [ 1 5 ]

-What is the product of matrices A and B?
A = [4 2] B=[1 5]
3 5 3 2 - -AB = [ (4)(1) + (2)(3) (4)(5) + (2)(2)]
(3)(1) + (5)(3) (3)(5) + (5)(2)
= [ 10 24 ]

, -In a traverse with a total length of 2180.91 m, one course has a latitude of 380.00 m and a
departure of 0.00 m. The closure of the traverse in latitude is 0.042 m and in departure is
0.145 m. What is the adjusted latitude and departure for that course if a compass rule
adjustment is used? - -lat adj= = (course dist./total dist.)(lat error)
=(380.00/2180.91)(0.042)
=0.007 m
depart adj = (course dist/total dist.)(depart erro)
= (380.00/2180.91)(0.145)
=0.025 m
380.00 - 0.007 = 379.993 (adj. lat)
-What is the arc length of a horizontal curve with coordinates as shown and a radius of
1000.0 ft? All distances are in feet.

-What is the length of a 100 ft steel tape with a cross-sectional area of 0.003 in² and a
modulus of elasticity of 30,000,000 lbf/in² that is standard at a tension of 10 llbf if it is
pulled at a tension of 20 lbf at standard temperature? - -tape length = 100 ft + 0.01 ft
= 100.01 ft
-What is the length of side b in the illustrated triangle if the area is 43,560 ft²? - -388.45

197.00 ft
-What is the length of the illustrated circular highway curve if the radius is 2000 ft? - -
2234.02 ft
-A retracement survey of a portion of a public land survey township results in the
coordinates shown. The distances in the illustration are those provided in the original
government survey, in chains. What are the correct coordinates, in feet, for the lost
southeast corner of Section 6? All coordinates are in feet. - -10,152.87, 15,254.42
-At a primary tide station, the gauge reading of mean tide level is 5.25m, and the long-term
mean range of tide is 1.45 m (Both values are from the latest national Tidal Datum Epoch.)
Simultaneous tidal observations are conducted for one month between the primary station
and a nearby point. The values listed are the mean values for the month of observation. The
same ratio exist between the observed range and long-term mean range at both stations.
What is the mean tidal range at the new station? All values are in meters
