A sloping line 392.40 m long was measured using a 50 m steel tape weighing 0.075 kg/m which was standardized at 15°C and 25 N pull. The difference in the elevation between the initial and end point was 2.25 m. If the measurement was undertaken with a temperature of 20°C and the tape was supported at both ends with an applied pull of 50 N. The cross-sectional area of the tape is 5.25 mm^2 and E=200GPa. Determine the corrected length of the horizontal line.
