A steel tape is standardized at 20°C. It is used to measure a line in a mine at 35°C. If the coefficient of linear expansion of the tape is positive, what correction should be applied to the measured length due to temperature?

Add a correction because the tape becomes longer at higher temperature

A tape is standardized under a pull of 50 N but used in the field under a pull of 80 N. Assuming elastic behavior, what is the sign of pull correction to the measured length?

Positive, because higher pull elongates the tape and increases true length
