The term scale comes from the Latin Scala, it is basically the ordered succession of a set of terms of the same quality. The scale of a unit refers to the measure that must be taken into account when reducing or enlarging something so that its physical or drawn representation is easier to interpret, for example, a giant building needs a smaller scale model to That engineers and architects can better visualize its geometry, another serious example, a small part of a car engine must be maximized on a plane, with its respective projections in order to be able to make its characteristics.
The scale is most commonly represented by a stepped line or straight divided into equal parts in which each step or line segment represents a unit, such as centimeters (cm), meters (m) and kilometers (km), these scales are with the purpose of recreating proportional distances and dimensions on a plane or map. Scale is also the proportion or size in which an idea or project is developed: "We must make an investment on a smaller scale to experience the feasibility of the project, if it turns out, that scale will be increased."
In the field of drawing, scale plays a fundamental role, and from there its respective series of uses takes root, leading to the mass production or construction of products and buildings. Engineers and machine operators must have a basic notion of what they are doing. For example, to make a screw it is necessary to enlarge said piece on a plane in order to see exactly how much thread it has, see the exact geometry of the head, its dimensions, strength and resistance so that it can be built, then It will be assigned a scale of force comprised, in which the screw will remain and will be identified at the time of its acquisition for a specific use, these scales are mostly resistance, weight or size.
