CM 2105 FINAL EXAM 2025-2026 DELATTE
LSU QUESTIONS AND CORRECT ANSWERS
GRADED A+
When laying out a building, points are going to be set at a prescribed distance
taken from the plans or from calculations. This is referred to as __________.
A) marking territory
B) measuring a distance
C) closing the loop
D) laying out
D) laying out
.
__________ length describes the length the chain should be.
Chain
Breaking __________ is a process that is used to measure up steep slopes. This
involves measuring in lengths shorter than the full chain length.
,Random chaining errors are predictable, follow the laws of math/physics, and can
be removed by calculation. True/False
False
Possibly the greatest source of error in chaining is that the users are not familiar
with the chain. True/False
True
False
Chain length is used to express the distance measured in thousandths of feet.
What type of laser does not have to be checked for calibration?
All lasers should be checked for calibration
a. Contour displays steepness or flatness
b.
, Match the description to the correct contour characteristic.
a. The horizontal distance between adjacent contours indicates the steepness of the
slope of the ground between the contours. When the contours are relatively close
together, the slope is comparatively steep, and when the contours are far apart, the
slope is gentle.
b. This is a very important characteristic that must be followed exactly when a field
engineer is attempting to draw contours from spot or grid elevations.
c. If a person starts at any point on a contour and follows the path of the contour,
they will eventually return to the starting point.
Laying Out More "Subtract the Correction"
Laying out distances between 2 points, one known and one unknown, with a long
tape will result in an inaccurate measurement. How should the correction for this
mistake be applied?
The 3/4/5 triangle can be used to establish parallel lines.
True/False
False
