Why Won't My Tape Measure Retract? Repairing a Broken Measuring Tape

This is highly annoying: a tape measure that does not retract… so today, we look at a broken measuring tape to understand how it works, so that we can repair it!
Note: The spring powered retraction mechanism can be damaged due to aging of the metal spring or because someone yanked too hard on a fully extended tape measure. In any cases, rolling the tape tightly while maintaining spring tension is the only thing needed to get back a fully functional measuring tape!
