Question: A surveyor's steel measuring tape is exactly 30 m long at 15°C when subjected to a pull of 45 N. Determine the correction to be made in reading the tape if it is used at 35°C under a pull of 70 N. The tape is 0.8 mm thick and 10 mm wide. Express the correction in millimeters per meter of length and indicate whether it is added to or subtracted from the reading.
