A steel tape was exactly 30 m long at 20°C when supported throughout its length under a pull of 10 kg. A line was measured with this tape under a pull of 15 kg and at a mean temperature of 32°C and found to be 780 m long. The cross-sectional area of the tape = 0.03 cm², and its total weight = 0.693 kg, α for steel = 11 × 10^-6 per °C and E for steel = 2.1 × 10⁶ kg/cm². Compute the actual length measured by the tape (up to two decimal places) if it was supported at every 30 m during measurement.
