Abstract
In this experiment, the concepts of measuring horizontal distances using the
taping technique are explored. This is a widely known type of detailed survey called
Reconnaissance, in which data is collected in a field through experimentation and
using different measuring techniques. The taping technique has its own sources of
errors and imperfections because of the factors such as the tape is not the standard
length which is a systematic error, poor alignment of the tape, change in temperature,
the elasticity of the tape that depends on the material that forms the tape, and some
personal errors. In the field, the students were asked to mark 4 vertexes of an enclosed
quadrilateral area and then the lengths of each side and the diagonals were measured
using the steel tape. After measuring the horizontal distances, some corrections had to
be done and taken into consideration, and thus, the formulas of corrections were used
to account for these errors caused by the measuring tape, outside temperature, and the
pulling tension. In the end, the angles were computed using the Sin and Cosine rules
using the horizontal distances measured and then the distance L6 was compared with
the originally drawn figure from AutoCAD and resulted in a percentage (%) error of
3.819%. Therefore, we have concluded the steel measuring tape is one of the most
precise and accurate measurement techniques that can be used in conducting an
experiment. [Show Less]
