While measuring three segments of a base line, the following data were obtained. Length (m) Temp. ("C) Pull (kg) Difference in level Segment No. of supports (m) 28.084 18 0.3 2 29.936 20 8 0.7 3 30. 115 28 10 0.5 The 30 m steel tape was standardized at 25'C under a pull of 5 kg. What are the correct "gths of segments? The tape weight 1.2 kg. Unit weight of steel is 7800 kg/m and coefficient of Dermal expansion is 1 1 x 10 5 "C ! Take E = 2.1 x 10' kg/mm
