A steel tape was exactly 30 m long at 20°C and under standard pull of 10 kg. A line was measured with this tape under a pull of 15 kg and at a mean temperature of 35°C and found to be 600 m. The cross sectional area of the tape is 0.03 cm2 and ∝ for steel = 12 × 10-6 per °C. E for steel = 2 × 106 kg/cm2. Compute the true length of the line in m?
