A steel tape of nominal length 200 m with a plumb bob of mass 16 kg attached to it was used to measure a length down a shaft as 160.852 m. The mean temperature during the measurement was 4 C. If the tape was standardized to be 200.0014m under a tension of 115 N at 20" C temperature, determine the correct measured length. The following data may be used: Mass of tape = 0.07 kg/m Cross-sectional area of tape= 10 mm Coefficient of linear expansion a = 11x 10/°C Modulus of clasticity = 2x 10° Nmm Acceleration due to gravity 9.807 m's.
