Measuring tapes and ruler
The simplest measuring tool, a ruler, is used to measure the length. Depending on the needs and the place of application, they can be strip, metal, wooden, soft, or laser. In-car workshops, measuring tape and machinist’s rules are used.
Measuring tape
Measuring tapes are a flexible type of ruler in the form of sheet metal that is wound into a housing with a spring return mechanism. Can be of different lengths, usually 2, 3, 5, 8, and 10 m. The measuring tape is pulled from the housing to measure items, and a spring return winds it back into the housing. There is a locking mechanism on the housing that holds the extended measuring tape to the desired length.
Measuring tape
Lengths with large, medium and small lines are marked on the measuring tape. There is a distance of 1 cm between every two lines. A small and a middle line are placed between the two large lines. The middle line represents 5 mm. Each small line determines the length in mm, which is the smallest measure of the measuring tape.
The machinist’s rule looks like a ruler and is made of metal (steel, aluminum). The measuring scale is located on the edge of the rule and is divided into divisions. The minimum dimension is 1 mm. They are used to measure and mark out items. Protect the machinist’s rule from damage by storing it carefully. A damaged ruler will not give an accurate measurement because it determines the beginning of the measure. If damaged, it may affect the accuracy of the measurements.
