In summary, for engineering systems both F and M can be considered fundamental because of the engineering definition of weight in addition to Newton s second law. However, this results in a redundancy, which needs to be recified by the conversion factor gc. The value of this conversion factor in the various engineering units provides the following identities ... 

Conceptual design studies for WIPP have been completed and architect engineering definition is now underway. A DOE Preliminary Environmental Impact Statement will be released by January, 1979. Present schedules call for construction to start in 1981 and for completion in 1985. First radioactive waste shipments could be accomodated in the spring of 1986. 

Do not attempt to compare fluid types as defined here with the reservoir descriptions as defined by the state regulatory agencies which have jurisdiction over the petroleum industry. The legal and regulatory definitions of oil, crude oil, gas, natural gas, condensate, etc., usually do not bear any relationship to the engineering definitions given here. In fact, the regulatory definitions are often contradictory.

In Table 3, reactor specifications and experimental conditions used and efficiency obtained for the different reactors are compared. A more practical engineering definition for efficiency is used instead of more scientific quantum efficiency. The efficiency of each of the reactors, expressed in terms of 50% pollufanf converted per unit time per unit reactor volume per unit electrical power consumed, is compared for the same model component (Orange II dye) and same initial concentration... 

In this equation, the chemical engineering definition of pp is used.

In the majority of mechanical applications of materials, their surfaces experience contact with another material and take the external load before the bulk of the material is influenced. In some cases, surface interactions influence the bulk (e.g., propagation of cracks dislocations or point defects from the surface in depth). In many cases, only the outermost surface layer is affected by the surface contact with no detectable changes in the bulk of the material. This is like a storm that is frightening and destructive on the ocean surface, but does not have any influence on deep-water life. We are primarily concerned in this review with that kind of interaction. The surface layer thickness affected by external mechanical forces ranges from nanometers to microns. Thus, in our case, the definition of surface is different from the one used by surface scientists, that is, physicists and chemists. We introduce here an engineering definition of surface the outermost layer of the material that can be influenced by physical and/or chemical interaction with other surfaces and/or the environment. In this chapter, we consider only mechanical effects, but both mechanical and chemical interactions are possible and their synergy can lead to mechanochemical alteration of a material surface. 

The importance of any engineering subject is calculated by two factors risk and cost. While risky is an unscientific way of addressing an issue that is potentially dangerous, risk has a clear engineering definition risk is the product of likelihood and consequences. These factors are expressed in a risk assessment matrix Figure 1.2 shows an example of a risk matrix. 

The construction interface. Inevitably this starts with the engineering definition of what construction work is required, to what standards, and how the work will be packaged. This leads to a follow-up stage in which construction information is issued, mainly in the form of drawings, and technical problems are resolved (requiring a site interface).

Yield stress may be regarded most simply as the minimum stress at which permanent strain is produced when the stress is subsequently removed. Although this deformation is satisfactory for metals, where there is a clear distinction between elastic recoverable definition and plastic irrecoverable deformation, in polymers the distinction is not so straightforward. In many cases, such as the tensile tests discussed above, yield coincides with the observation of a maximum load in the load-elongation curve. The yield stress then can be defined as the true stress at the maximum observed load (Figure 11.8(a)). Because this stress is achieved at a comparatively low elongation of the sample, it is often adequate to use the engineering definition of the yield stress as the maximum observed load divided by the initial cross-sectional area.

After such criticisms he suggests engineering definition from the historical point of view as follows. 

Reflecting on the findings by Aven, it is found that the traditional engineering definitions (Cl and C6) and the definitions of decision analysts (Cl) are the predominant views on risk, (Aven 2012b). Aven in (2012b) claims that the risk definitions of category C8 (R = C U), where uncertainty rather than probability is seen as a fundamental component of risk, have recently replaced probability-based conceptualizations in the engineering fields. From our analysis, it is seen that this is not the case for the maritime transportation application area. In fact, such a view on risk is not found. 

Finally, the definition concludes with the idea of safety, an objective that is ultimately more important than either the economic or aesthetic ones, for the loss of a single life due to structural collapse can turn the most economically promising structure into the most costly and can make the most beautiful one ugly. The structural engineers definition comes to an end with the idea that structures are safe if they can resist the forces to which they may be subjected, but it is symbolic of the virtually endless list of forces to which a structure might in fact be subjected that there is no period at the end of what seems otherwise to be a complete sentence.
