A STRAIGHT LINE IS DETERMINED TO BE 3234.25 m WHEN MEASURED WITH A 50-m STEEL TAPE SUPPORTED THROUGHOUT ITS LENGTH UNDER A PULL OF 4.5 kg AND AT MEAN TEMPERATURE OF 35°C. DETERMINE THE CORRECT LENGTH OF THE STRAIGHT LINE IF THE TAPE USED IS STANDARD LENGTH AT 30°C UNDER A PULL OF 6 kg. THE CROSS-SECTIONAL AREA OF THE TAPE IS 0.03, ITS COEFFICIENT OF LINEAR EXPANSION IS, AND THE MODULUS OF ELSTICITY OF STEEL IS 2.0 × (2) kg/cm²
