Anna University Regulation 2017 MECH ME8501 MM 2marks & 16marks for all 5 units are provided below. ME8501 MM Short answers, Question Bank for METROLOGY AND MEASUREMENTS Engineering are listed down for students to make perfect utilization and score maximum marks with our study materials.


1. What is Range of measurement?
The physical variable that is measured between two values is called as a range. One is  the higher calibration value H, and the other is Lower value L, The difference between H, and L,  is called range.
2. What is Resolution?
The minimum value of the input signal is required to cause an appreciable change in the  output known as resolution.
3. Differentiate between sensitivity and range with suitable example.
Example: An Instrument has a scale reading of 0.01mm to 100mm. Here, the sensitivity  of the instrument is 0.0lmm i.e. the minimum value in the scale by which the instrument can read. The range is 0.01 to 100mm i.e. the minimum to maximum value by which the instrument  can read.
4. Define system error and correction,
Error: The deviation between the results of measured value to the actual value.
Correction: The numerical value which should be added to the measured value to get the correct result.

8. Give any four methods of measurement
1. Direct method.
2. Indirect method.
3. Comparison method.
4. Coincidence method.
9. Give classification of measuring instruments.
1. Angle measuring Instruments.
2. Length measuring Instruments.
3. Instruments for surface finish.
4. Instruments for deviations.
10 .Define True size:
True size is Theoretical size of a dimension
11. Define Actual size
Actual size = Size obtained through measurement with permissible error
