Various machine components used in mechanical engineering. Mechanical engineering is the study of physical machines that may involve force and movement. It is an engineering branch that combines engineering physics and mathematics principles with materials science, to design, analyze, manufacture, and maintain mechanical systems. [1]
Yield point – In materials science and engineering, the yield point is the point on a stress–strain curve that indicates the limit of elastic behavior and the beginning of plastic behavior. Below the yield point, a material will deform elastically and will return to its original shape when the applied stress is removed.
A material take off (MTO) is the process of analyzing the drawings and determining all the materials required to accomplish the design. Thereafter, the material take off is used to create a bill of materials (BOM). Procurement and requisition are activities that occur after the bill of materials is complete, distinct from Inspection.
An engineering bill of materials (EBOM) is a type of bill of materials (BOM) reflecting the product as designed by engineering.. The EBOM is not related to modular BOM or configurable BOM (CBOM) concepts, as modular and configurable BOMs are used to reflect selection of items to create saleable end-products.
In brittle materials the ultimate tensile strength is close to the yield point, whereas in ductile materials the ultimate tensile strength can be higher. Tensile testing Tensile testing, also known as tension testing, [225] is a fundamental materials science and engineering test in which a sample is subjected to a controlled tension until
The term bent is not restricted to any particular material. Bents may be formed of wooden piles, timber framing, [17] steel framing, or even concrete. [18] Bistable structure – Brick – is building material used to make walls, pavements and other elements in masonry construction.

An order from the engineering department (to be followed by the production department or vendor) overriding/superseding a detail on the drawing, which gets superseded with revised information. Also called by various other names, such as engineering change order (ECO), engineering change notice (ECN), drawing change notice (DCN), and so on.
