Introduction to Technical Measurement - Fill in the Blanks Points : introduction to technical measurement, fill in the blanks, objective type question and answer, metrology, mechanical technology Fill in the Blanks
  1. A set of experimeita1 operations carried out with the object of determining the value of a quantity is called Measurement.
  2. The operation consisting of obtained the indication of the measuring instruments is called Observation.
  3. The weighing scales in a local market are calibrated against national Standard weights.
  4. Scientific or fundamental metrology concerns the establishment of measurement units.
  5. Legal metrology concerns regulatory requirements of Measurements and measuring instruments for the protection of health & public safety.
  6. The metric system became compulsory in the Netherlands from 1816 and was chosen by Spain in 1849.
  7. Measurement is an Observation that reduces an uncertainty expressed as a quantity.
  8. A system of Measurements is a set of units which can be used to specify anything which can be measured.
  9. Metric systems of units have evolved since adoption of the first well-defined system at 1791 in France.
  10. Inspection is the function to judge the Quality a product.
  11. Inspection is the art of comparing materials Product or performance with established standards.
  12. Inspection is an important aspect of Production
  13. To maintain the desired accuracy and quickness controlling the quality of a Product
  14. Quality control inspector must know statistical quality control Techniques programme well.
  15. Quality inspector should be able to minimize or Prevent wastage by using a substitute to the material already in use.
  16. Inspection standards for raw material are based upon Purchase specification.
  17. Complex and elaborated gauges and fixtures are used for the inspection of such Finished products.
  18. To see that proper care of costly equipment in inspection department is being taken is the responsibility of Chief Inspector:
  19. Lot by lot inspection method is also known as Sampling Inspector.
  20. Inspection may be done wither at the machines or in a central inspection room Separated form actual production.
  21. Inspection prevents the delivery of defective products to the Customer.
  22. Industrial inspection has emerged as a powerful tool for Management.
  23. Most important parameter in metrology is Observation.
  24. The term manufacture implies that the parts which go into an Interchangeable assembly may be e1ected at random from large number of parts.
  25. The metric system was originated in France.
  26. The British system of linear measurement is based on arbitrary unit known as Yard.
  27. A Yard or Meter is defined as the distance between scribed lines on a bar of metal under certain conditions of temperature and support.
  28. Precision is defined as the repeatability of a measuring process.
  29. Accuracy is the agreement of the result of a measurement with the true value of the measured quantity.
  30. Controllable errors are also known as Systematic errors.
  31. A Measuring instruments is any device that, may be used to obtain a dimensional or angular measurement.
  32. International organization of weights and measures was established in the year 1980.
  33. A Gauge is a tool r instrument used to measure or compare a component.
  34. Metrology is the knowledge dealing with the problem of measurements.
  35. The operations conducted with a view to verify that the measuring instruments confirms to a standard is called Examination.
