2. A 50 m. steel tape is of standard length under a pull of 5.5 kg. when supported
throughout its length. The tape weighs 0.05 kg/m, has a cross sectional area of 0.04
sq. cm. This tape was used in the field to measure a distance that was determined to
be 488.65 m. At the time of measurement, the constant pull applied was 8 kg. with
the tape supported only at its endpoints. Determine the correct length of the line.
3. A 50 m tape was standardized and found to be 0.0015 m longer at an observed
temperature of 31.5°C under a pull of 10 kg. The same tape is used to measure a line
found to be 523.61 m at an average temperature of 24.5 °C using a pull 12 kg. What
is the correct length of the line?
4. The distance from point A to B was measured with a steel tape weighing 3 kg at a
temperature of 34°C with a standard pull of 10 kg. and supported at 25 m intervals.
The measured distance was 99.992 m. If the standard temperature of the tape is 27°C
and point B is higher than point A by 6.5 m, compute the correct horizontal distance
between A and B.
