Final answer:
Dimensioning mechanics involves adding dimensions to a mechanical drawing to communicate the size and specifications of an object, including what dimensions look like, where they are placed, and which dimensions are chosen the correct option is d.
Step-by-step explanation:
Dimensioning mechanics refers to the process of adding dimensions to a mechanical drawing to communicate the size, shape, and other specifications of an object. It involves specifying the measurements of various features like length, width, and height, as well as any necessary tolerances.
Dimensioning mechanics involves all of the options listed: what dimensions look like, where dimensions are placed, and which dimensions are chosen.
The best definition for dimensioning mechanics is the practice involved in documenting the size, location, and specification of individual features on a technical drawing or blueprint.
This process includes determining which dimensions are required to effectively communicate a part's size, shape, and tolerances, where those dimensions should be placed on the drawing for clarity and conformity to drafting standards, and how the dimensions themselves are to be presented visually (like line type, arrowheads, etc.).
Therefore, the answer to the question is 'd. all of the above,' since dimensioning mechanics encompasses all these aspects
