Question

True/False Indicate whether the statement is true or false. 1. True north longitudinal lines are parallel. (1 Point) 2. Parallax is a possible source of error for leveling but not for traversing. (1 Point) 3. Plunging the scope is one way to clean the instrument. (1 Point) 4. When using a transit or total station, the angular accuracy for long sights is better than for short sights. (1 Point) 5. Highway engineers use the arc definition for horizontal curves. (1 Point) 6. Magnetic north direction does not change. (1 Point) Lists s of error in surveying, leveling, chaining, and/or traversing. (I point for each correct ng answers. The following examples of general 7. List up to 12 sources answer up to 12 points.) NO SUBTRACTION for wro errors are not accepted - you must be more specific: Human error, personal error, random errors, or math error weather, systematic error 6. 8. 10. 12.

Explanation / Answer

1) True. True north longitudinal lines are always parallel.

2)False. Parallax error occur due to wrong measurement of reading. So, it will come anywhere.

3) False. Plunging the scope will not be a cleaning process.

4) True. For longer sight, angular measurement is accurate but not for the shorter disatnces.
