CE 301 Test 1 2026/2027 Exam
Questions and Answers |
Already Graded A+
Pacing - ANSWER ✔✔Approximate Measurement. Length of pace
that can be comfortably repeated. Important uses: distance between
markers, key points in construction layouts; 1/100 accuracy ratio
Odeometer - ANSWER ✔✔automobile odometers - Assist in
identifying platted property lines. Measuring wheels - where low order
precision is acceptable (1/100 - 1/200)
EDM - ANSWER ✔✔Electronic Distance Measurement. Function by
sending light wave along the path to be measured form the instrument
station, and then the instrument measures the phase difference between
,the transmitted light wave and the light wave as it is reflected back to its
source from a reflecting prism at the second point.
Woven tapes made of linen, Dacron, and the like - ANSWER ✔✔fine
copper strands interwoven to provide strength and to limit deformation
due to long use and moisture.
Problems with EDM for short distances - ANSWER ✔✔1. the time
involved setting up the EDM and the prism, 2. The unreliable accuracies
in some short-distance situations.
steel tape - ANSWER ✔✔Valuable tool. Most precise, next to EDM,
best for short distances.
Invar tapes - ANSWER ✔✔35% nickel, 65% steel. Alloy has very low
coefficient of thermal expansion.
Plumb Bob - ANSWER ✔✔used in taping to transfer from tape to
ground when the tape is being held off the ground to maintain its
horizontal alignment.
Hand level - ANSWER ✔✔used to keep the steel tape horizontal
when measuring.
Range poles - ANSWER ✔✔used in taping and theodolite work to
provide alignment sights.
, Clamp handle - ANSWER ✔✔Grips the tape at any intermediate pint
without bending or distorting the tape.
Tension handles - ANSWER ✔✔Used in precise work to ensure that
the appropriate tension is being applied.
Chaining pins - ANSWER ✔✔used to mark intermediate points on the
ground. In route surveying - whole set is used to mark out the centerline.
In rear surveying - responsible for checking the number of whole tape
lengths by keeping an accurate count of the pins collected.
Tape repair kits - ANSWER ✔✔include: punch plier and repair
eyelets, steel punch block and rivets and tape repair sleeves.
Plumb bob target - ANSWER ✔✔used to provide alignment sights
Breaking Tape - ANSWER ✔✔When a slope is too steep to do
horizontal tape measurement, shorter horizontal measurements are
taken. The shorter measurements are totaled to provide the overall
dimension. Increases chance of random errors
Systematic taping errors (4) - ANSWER ✔✔1. Slope
2. Erroneous length
3. Temperature
3
