SITUATION 03 A tape of 30 m length suspended in catenary measured the length of a base line. After applying all corrections the deduced length of the base was 1,462.36 m. Later on, it was found that the actual pull applied was 155 N and not 165 N as recorded in the field book. The tape was standardized on the flat under a pull of 85 N having a mass of 0.024 kg/m and the cross-sectional area of 4.12 mm². The modulus of elasticity of the tape material is 152 GPa and the acceleration due to gravitv is 9 806 m/s². a) Give the correction for the measured line (in meters) due to suspension of the tape. b) Give the corrected length (in meters) of the base line?
