Under a pull of 145 N and mean temperature of 14 °C, a line was measured by a tape suspended in catenary. In standard condition, the tape has a pull 95 N at 18 °C. The lengths of various segments of the tape and the difference in level of the two ends of a segment are given in the table below: Length (m) Difference in Bay/Span level (m) 1 29.988 + 0.346 29.895 - 0.214 29.838 + 0.309 4 29.910 - 0.106 Take: Cross-sectional area of the tape = 3.35 mm2 Mass of the tape = 0.025 kg/m Coefficient of linear expansion = 0.9 x 10-6 per °C Young's modulus = 14.8 x 104 MN/m2 Mean height of the line above M.S.L. = 51.76 m Radiur of onrth 6270 km 3.

Length and Length related Variables

Length can de defined as the measurement or extent of physical quantities or objects from one terminal to another terminal. Stone age humans used finger length, step length, and so on to measure the size or displacement of an object. Nowadays, depending on how precise the measurement requires to be and the object’s size is measured, we use measuring devices for measurements like rulers and steel tape. Most people have used a ruler or tape measure to measure a particular distance or the size of an object. For more precise measurements of tiny objects, the development of measurement tools such as the Vernier caliper, which permits us to measure dimensions within 1/1000 of an inch. In the last few decades, electronic distance measuring instruments (EDMI) have been implemented that permit us to measure distances from a few feet to many miles with reasonable accuracy.
