hello! help me please huhuhu. Thank you very much! Problem 6. A baseline was measured using a 100mtape which is standardized at 15°C with a standardpull of 10kg. The recorded distance was found tobe 430.60 meters. At the time of measurement,the temperature was 20°C and the pull exertedwas 16kg. Determine the true length of the baseline if the weight of one cubic cm steel is 7.86grams. Weight of tape is 2.67 kg. E is 2 x 106kg/cm? and K is 7 x 107 (m/m-°C)

To find :- True length of Base line After applying correction for temperature and pull to tape.

Answered: Problem 6. A baseline was measured…

In every measurement, a 100-meter tape is suspended at the ends under a pull of 15 kg. It isalso supported at 30 m and 75 m marks. If the tape is used to measure a 543.25 long line,determine the total correction due to sag? The tape weighs 5 kg.
A line was found to be 2,395.25 m long when measured with a 30 m tape under a steady pull of 3 kg. at a mean temperature of 30°C. The tape was held in the air and supported at both ends and at every one third of the tape. Determine the correct length of the line if the tape used is of standard length at 20°C under a pull of 5 kg. Assume the cross-sectional area of tape to be 0.02 cm2, Elastic Modulus as 2.10 x 106kg/cm2, weighs 0.05 kg/m, and a Coefficient of Thermal Expansion to be 0.0000116/°C.
Jisoo used a 40 meter steel tape in measuring an inclined distance on a gentle slope. The sloping distance was recorded to be 440 meters long. The difference in elevation between the initial point and the end point was found to be 32.49 m. The 40-meter tape is of standard length at a temperature of 20 °C and a pull of 34 N. During measurement, the temperature reading was 44 °C and the tape was supported throughout its length with an applied pull of 82 N. The cross-sectional area of the tape is 1.54 mm^2 and the modulus of elasticity is 200 GPa. The tape has a mass of 0.68 kg. Determine the corrected horizontal distance in meters. Round off to two decimal places.
