Probable Error - a. b. Example 2 PLANE SURVEYING SU1200 ASSIGNMENT 1 1. The sides of a closed figure have been measured and found to have a total length of 1018.910 m. If the error in the measurement is estimated to be 0.073 m, what is the accuracy ratio of the work? 2. A random error of ± 0.004 m is estimated for each of 22 length measurements (which are to be added together to get the total length). what is the estimated total error? what is the probable total error if the random error is ± 0.006 m per length? 3. A surveying crew or party is capable of taping distances with an estimated probable error of ± 0.005 for each 30.000 m distance. What estimated total error should be expected if a distance of 1400 m is measured? 4. It is desired to tape a distance of 360 m with a total estimated probable error of not more than ± 0.006 m. a.
