Measured length of the bolt is 2.6 inches.

To Find :

The percent error of the bolt.

Solution :

We know, percentage error is given by :

`\delta =| (Actual\ Value - Expected\ Value)/(Expected\ Value)|* 100\\\\\delta =| (2.6-2.5)/(2.5)|* 100\\\\\delta = 4 \%`

Therefore, the percentage error in the bolt is 4% .
