A steel tape has nominal length 30.000 m. was used to measure a base line A to B. The standard conditions were temperature 20°C, actual tape length 30.005 m., with tension 100 N, expansion coefficient 11.2x10-6/1°c, area 4 mm2, weight 0.0193 kg./m., E 2.2x105 N/mm2, g = 10 m/sec2. Field condition: AB: (distance measured above the ground) 52.1234 m, tension 10 kg, temperature 39°C question1: How many correction have to adjust for the base line AB measurement?
