Next up, that metal cap on the end of a tape measure may seem as though it is loose and needs fixing,

this stops the cap's size being added to the length measurement. The opposite occurs when the

cap is hooked onto a surface, because the cap no longer adds length by being in the way, it extends so the

measurement can be taken from the exact same point on the tape measure. By accounting for the
