A drawing of the object in scale.
For good pay scale, after completing mechanical engineering the courses are CSWIP CERTIFICATION COURSE, DESIGNING, CAD/CAM, or else plan for MS if it is affordable.
This is a method used to determine the hardness of a metal. If you know the type of metal and the hardness, this will tell you the Tensile Strength of the metal and how well it was heat treated. The method uses a ball or a pin to strick the metal and leave a small indention. The size and depth that the ball makes in the metal is inversely proportional to the hardness. Using the scale, you can then determine if the part has completed the proper heat treatment as required by the Engineering drawing. There are 3 Rockwell scales: A, B, C. Rockwell C scale is for the hardest of metals such as steel. Rockwell B is for metal such as soft aluminum and A is for even softer metals.
It can't be accurately converted.The softest metal on the C scale gets a 1 rating.That 1 rating is the equivalent of 82 on the B scale, which is the Rockwell scale used for copper.Copper and all it's alloys are down around the 40 range of the B scale.And you can't assume that a B scale 40 is half of a C scale 1, either. Since the tests use different metal ball sizes, it's an issue of being an unequal scale.
Answer Rockwell C is a method to measure the hardness of a metal object. The hardness of the metal is a direct correlation to its strength properties: i.e., Tensile Strength. The scales can be found in any engineering or matierals reference books. A test devise is used to strick a metal object with a small pointed hammer. The size of the dimple is compared to a chart to give you the Rockwell C hardness value. There are 3 charts for measuring hardness: A scale, B scale and Cscale. Rockwell C is for the hardest of metals such as very high strength steel. Rockwell A is for much softer materials including something as soft as clay, I believe. During manufacture, a hardness test will be performed to ensure that the finished product meets the design engineer's criteria to ensure the part.
An underline on a dimension means that it is not to scale.

It is a scale drawing
Scale provides the ability to measure a depicted feature or arrangement of features on the drawing, and scale it to what it was / will be in the real world. It is not always possible to dimension every possible feature, and a scaled drawing allows someone to infer what a given dimension will be.

I need help in drawing to scale for landscaping purposes. If the dimension is any more complicated than a 10 x 10 square, I can't seem to get the scale right. I need Drawing to Scale for Dummies. Help.
No, an object is a physical entity with three-dimensional properties, while a scale drawing is a two-dimensional representation of the object's dimensions in a smaller or larger scale. Scale drawings provide a visual representation of an object's proportions and layout, but they do not capture the full physical characteristics of the actual object.
A linear scale, also called a bar scale, graphic scale, or graphical scale, is a means of visually showing the scale of a map, nautical chart, engineering drawing, or architectural drawing.:))

If the scale is 1 to 16, then each dimension in the real world is 16 times its size on the drawing, and its size on the drawing is 1/16 of its real size. The barn must be drawn 2-ft high on the plans.
Scale conversion refers to changing the size of an object or drawing in proportion to the original size. This is commonly done when creating architectural or engineering blueprints, maps, or models to ensure accurate representation at a different scale. It involves using a scale factor to calculate the new dimensions based on the original dimensions.
