A 50m tape of std. length has a weight of 0.05kg/m, with a cross sectional area of 0.04cm2. It has an E of 2.10x10°kg/cm². The tape is of std. length under a pull of 5.5kg when supported throughout its length and a temp. of 20°C. This tape was to measure a dist. bet. A and B and was recorded to be 458.65m. At the time of measurement, the pull applied was 8kg with the tape supported only at its end points and the temp. observed was 18 C. Assuming a of the tape is 0.0000116/°C. Compute the true length of the measured line AB due to combined effects of

Transcribed Image Text:A 50m tape of std. length has a weight
of 0.05kg/m, with a cross sectional area
of 0.04cm?. It has an E of
2.10x10°kg/cm². The tape is of std.
length under a pull of 5.5kg when
supported throughout its length and a
temp. of 20°C. This tape was to measure a
dist. bet. A and B and was recorded to be
458.65m. At the time of measurement,
the pull applied was 8kg with the tape
supported only at its end points and the
temp. observed was 18°C. Assuming a of
the tape is 0.0000116/°C.
Compute the true length of the measured
line AB due to combined effects of
temperature, tension and sag.
