Hi
What are the drawbacks of using elastic measuring tape?
Not like to use a measuring tape made of an elastic material like rubber to measure distance because an elastic measuring tape gives the incorrect length of the distance between two points.
Reasons -: (i) The length of the elastic tape varies and depends; upon the force by which it is stretched. (ii) Measurement would vary between 2 or 3 reading; even when measured by the same person and by the same elastic tape. (iii) Measurement would also vary if different persons measure the same distance. While telling the measurement taken with elastic tape, we have to tell whether the tape was stretched and by how much. This is very difficult.
