The Tape Measure is too deformed and will not fail. Why didn't it fail? The spring in the tape measure is very long, and it is completely relaxed to completely tighten the range. The entire stroke of the tape measure includes it, and there is margin at both ends, so the tape measure will not fail.
There is no difference in tension between a one-meter length and a two-meter length; the spring of the tape measure is very thin, and the amount of deformation when it is tightened is very small, so the reaction force is very small, and no force change is felt when the rule is pulled.
