What is the etymology of nominal?
nominal (adj.) mid-15c., nominalle, “pertaining to nouns,” from Latin nominalis “pertaining to a name or names,” from nomen (genitive nominis) “name,” which is cognate with Old English nama (from PIE root *no-men- “name”). Meaning “being so in name only” is recorded from 1620s.
What does within acceptable tolerances mean?
Tolerance refers to the total allowable error within an item. In this way, tolerance is meant to be used when setting the acceptable error range (the range within which quality can still be maintained) based on the design value with the assumption that variation will occur at any given step.
What do we mean by nominal?
Nominal is a financial term that has several different contexts. It can mean small or far below the real value or cost such as a nominal fee. Nominal also refers to an unadjusted rate in value such as interest rates or GDP.
What does System nominal mean?
Nominal systems are used to determine if types are equivalent, as well as if a type is a subtype of another. Nominal type systems contrast with structural systems, where comparisons are based on the structure of the types in question and do not require explicit declarations.
What is a nominal definition in research?
In statistics, nominal data (also known as nominal scale) is a type of data that is used to label variables without providing any quantitative value. It is the simplest form of a scale of measure. Unlike ordinal data. Thus, the only measure of central tendency. for such data is the mode.
What is a nominal phrase example?
“For example, in the noun phrase a nice cup of tea, it makes sense to say that nice is a modifier of a cup of tea, rather than just the head noun cup,” says Author Geoffrey Leech in “A Glossary of Grammar.” In this phase, “nice cup of tea” is a nominal; it provides more description than simply saying “cup.” Using a …
What does nominal mean in engineering?
In various subfields of engineering, a nominal value is one for which the “name” for the value is close to, but not the same as, the actual value. Some examples: For example, a pump is designed to deliver its nominal pressure and flow while operating at its nominal speed and power.
Why is there a tolerance allowed in measured values?
One of the reasons for establishing tolerances for practical applications is to find a balance between the processing cost and the intended functions of the object. Increases in accuracy lead to corresponding increases in processing costs.
What is a nominal suffix?
Nominal suffixes are often employed to derive abstract nouns from verbs, adjectives and nouns. Such abstract. nouns can denote actions, results of actions, or other related concepts, but also properties, qualities and the like. Another large group of nominal suffixes derives person nouns of various sorts.
Does nominal mean ideal?
You can think of ‘nominal’ as meaning ‘ideal’. Say you have a motor on the rocket, and it will only work if the temperature is between 50 and 100 degrees. Nominal would be 75 degrees. It’s the ideal temperature between too cold and too hot.
Which of the following can be described as a nominal variable?
A nominal variable is one of the 2 types of categorical variables and is the simplest among all the measurement variables. Some examples of nominal variables include gender, Name, phone, etc.
What is a nominal value of tolerance?
The aeronautical sense of nominal derives from engineering where the nominal value is the specified dimension and the reference point for tolerances. The Free Dictionary offers the following definition (from McGraw-Hill Dictionary of Scientific & Technical Terms, 6th edition) for tolerance:
What is the meaning of within acceptable tolerances?
This answer is correct, if a little long-winded. The meaning “within acceptable tolerances” can be derived from the idea “by name” quite handily. It means “close enough to call it that”. As @Drew has shown by example, “name” and “nominal” can be used to imply both favorable and unfavorable assesements.
What do you mean by tolerance in Mechanical Engineering?
Definition of Tolerance. A tolerance is the acceptable difference between the maximum and minimum size of a mechanical part as a basis for determining the accuracy of its fit with another part. For Example: A dimension gives as Ø 28±0.2 means that the manufactured part may be Ø 28.2 or Ø 27.8, or anywhere between these limit dimensions.
What is a measurement corresponding to the nominal value?
A measurement corresponding to the nominal value is “according to plan or design.” Similarly, when using bilateral tolerances the nominal value is by definition “within acceptable tolerances.” The aeronautical usage is derived from engineering.
