Mechanical Measurements Midterm 1
Questions and Correct Complete
Solutions
Whatever exists, exists in some amount answer - The determination of the amount is what
measurement is all about
Mechanical Measurements answer - Those measurements related to mechanical engineering
Measurand answer - The particular physical parameter being observed and quantified; that is,
the input quantity to the measuring process
Result answer - The act of measurement produces this
Standard answer - A predefined measurement upon which others are calibrated. Ex: The
international organization for standardization (ISO), the National institute of standards and
technology (NIST), formerly the National Bureau of Standards (NBS), or the American National
Standards Institute (ANSI).
Transduce answer - To change a mechanical measurand into a corresponding electrical quantity
Development answer - The final stage of the design procedure
Empirical Element answer - based on experience and on engineering common sense
Rational Element answer - Relies on engineering principles, the laws of physics, and so forth
, Experimental element answer - is based on measurement, that is the measurements of the
various quantities pertaining to the operation and performance of the device or process being
developed
Direct Comparison answer - A measurement compared to a primary or secondary standard.
Typically less common than indirect comparison due to innaccuracies in human interpretation.
Example: Measuring length using a ruler.
Indirect Comparison answer - A measurement compared to a calibrated system. Makes use of
some form of transducing device coupled to a chain of connecting apparatus, which is called the
measuring system. The chain of devices converts the basic form of input into an analogous
form, which it then processes and presents at the output as a known function of he input.
Secondary Standard answer - A standard whose ancestry goes back no more than four
generations to the primary standard
Measuring system answer - A transducing device coupled to a chain of connecting apparatus.
The measured quantity is converted from a mechanical form to an analogous form, which is
processed and presented at the output as a known function of the input.
Processing answer - Increases the amplitude or a power through some form of amplification, or
extracts desired information from a mass of extraneous input requiring filtering. Or can
remotely monitor a signal, convert to a radio wave, and transmit it.
Measuring System Stages answer - Stage 1: A detector-transducing or sensor-transducer stage
Stage 2: An intermediate stage, called the signal-conditioning stage
Stage 3: A terminating or readout stage
