The three bays of a base line were measured by a steel tape in catenary as 30.084, 29.973 and 25.233 m, under respective pulls of 7, 7 and 5 kg, temperatures of 12°, 13° and 17°C and differences of level of supports of 0.3, 0.7 and 0.7 m. If the tape was standardized on the flat at a temperature of 15°C under a pull of 4.5 kg, what are the lengths of the bays? 30 m of tape is exactly I kg with steel at 8300 kg/m. with a coefficient of expansion of 0.000011 per °C and E = 210 x 10 N/mm2.
