While the latter is derived to measure distances travelled by a vehicle, the former is specialized to measure distances. In the 17th century, the surveyor's wheel was re-introduced and used to measure distances. A single wheel is attached to a handle and the device can be pushed or pulled along by a person walking.
Two types of radius gauges. A radius gauge, also known as a fillet gauge, [1] is a tool used to measure the radius of an object. [2] Radius gauges require a bright light behind the object to be measured. The gauge is placed against the edge to be checked and any light leakage between the blade and edge indicates a mismatch that requires ...
A square is a tool used for marking and referencing a 90° angle, though mitre squares are used for 45° angles. Squares see common use in woodworking, metalworking, construction and technical drawing. [1] Some squares incorporate a scale for measuring distances (a ruler) or for calculating angles.
It has stem with ball at both ends. The length range of the stem depends upon the width of the part. If you want to measure the diameter set the gauges required diameter with master. [clarify] In order to measure the diameter of the bore, place the beam at one end and slide the other end on the diameter and watch the dial indicator. The values ...
a device used to measure the strain of an object. Thread pitch gauge, also called a threading gauge, pitch gauge, or screw gauge a device used to measure the pitch or lead of screw threads. Vernier height gauge: a measuring device used either for determining the height of something, or for repetitious marking of items to be worked on.
A combination square is a multi-purpose measuring and marking tool used in metalworking, woodworking, and stonemasonry. It is composed of a rule and one or more interchangeable heads that can be attached to the rule. [1] [2] Other names for the tool include adjustable square, combo square, and sliding square.
A compass, also commonly known as a pair of compasses, is a technical drawing instrument that can be used for inscribing circles or arcs. As dividers, it can also be used as a tool to mark out distances, in particular, on maps. Compasses can be used for mathematics, drafting, navigation and other purposes.
line length = wheel circumference × teeth counted/teeth on wheel. In more sophisticated models, sometimes called a chartometer, the wheel is connected via gearing to a rotary dial from which the line length can be directly read. [1] The instrument is most commonly used to measure the lengths of roads, rivers and other line features on maps ...
