SYSTEMATIC ERRORS IN TAPING #1 + COMBINED TAPE CORRECTIONS fA 30m tape weighs 12 g/m and has a cross section of 0.020 cmz. It measures correctly when supported throughout under a tension of 8.5 kg and at a temperature of 20C. When used in the field, the tape is supported at its ends only, under a tension of 8.5 kg. The temperature is 13. 5C. What is the distance between the O- and 30- -m marks under these conditions? Assume a = 0-116/ac and E _ 2.10 x 106 "Q/Cm SYSTEMATIC ERRORS IN TAPING '0' +CORRECTION DUE TO TEMPERATURE +A steel tape, known to be of standard length at 20C, is used in laying out a runway 2,500.00m long. If its coefficient of linear expansion of 0.0000116/C, determine the following when the temperature is 42C: v Temperature correction t Correct length to be laid out. SYSTEMATIC ERRORS IN TAPING + TAPE IS NOT OF STANDARD LENGTH * A building 38 x 45 m is to be laid out with 50-m long metallic tape. If during standardization the tape is found to be only 49.950 m, determine the following: + Dimensions to be laid out + Length of the diagonal
