A tape was suspended in four spans under a pull of 14.78 kg and mean temperature of 14°C. Each span was supported at its ends only. The table below shows the length of each spans. Span 1 2 3 4 Length (m) 29.988 29.895 29.838 29.910 The tape was standardized under a pull of 9.68 kg and a temperature of 18°C. The tape has a cross-sectional area of 3.35 mm², Modulus of Elasticity of 1.51 x 10¹ kg/mm², coefficient of thermal expansion of 0.0000009/°C, and a weight of 0.025 kg/m. A) Determine the correction due to temperature. B) Determine the correction due to tension/pull. C) Determine the total correction due to sag. D) Determine the corrected length of the whole line.
