Fundamentals of Surveying (FS) Practice Exam

What feature distinguishes an add tape?

1. The last foot of each end is graduated in tenths or hundredths of a foot

2. There is an extra graduated foot beyond the zero mark

3. There is an extra graduated foot at the 100-foot end of the tape

4. There is an extra graduated foot at both ends of the tape

The correct answer is: There is an extra graduated foot beyond the zero mark

An add tape is characterized by having an extra graduated foot beyond the zero mark. This feature allows the surveyor to make measurements in a more efficient manner. By having an additional graduated section, it provides a means for more accurate readings and allows for easier calculations without needing to consider the length of the tape itself starting from zero. This additional graduation is particularly useful in situations where the tape is anchored and measurements need to be taken to a point that is more than one full measurement length away, facilitating more straightforward adjustments during various survey tasks. The other features listed do not accurately describe an add tape. For instance, while graduation in tenths or hundredths is useful for precision measurement, it does not specifically distinguish an add tape from other measuring tapes that may have similar graduations. Additionally, extra graduations at the 100-foot end, or both ends, do not apply to the defining characteristics of an add tape, as the crucial element remains that extra foot beyond the zero mark.
