Theory and Design for Mechanical Measurements

Measurement is a term that refers to analyzing a manufactured component regarding the degree of accuracy for dimensions, tolerances, geometric profile, roundness, flatness, smoothness, etc. Measurement always involves comparing the manufactured component or the prototype with a standard specimen whose dimensions and other parameters are assumed to be perfect and do not undergo changes with respect to time.Precisely in mechanical engineering the branch that deals with the application of scientific principles for measurements is known as metrology. The domain of metrology in general deals with various measurements like mechanical, chemical, thermodynamic, physical, and biological measurements. In mechanical engineering, the measurements are limited to mechanical specific such as length, mass, surface profile, flatness, roundness, viscosity, heat transfer, etc.

Basic principles of engineering metrology

Metrology is described as the science of measurement, precision, and accuracy. In other words, it is a method of measurement based on units and predefined standards.

Shipra Manufacturing Company is thinking about development of a strong charge producing measure by adding one-ton limit during heaters. Each clump (one ton) of charge should go through 30 minutes of heater time, including stack and dump tasks. In any case, the heater potential use factor is just 80% because of stream limitations in different pieces of the framework. Required yield for the new design is to be 16 tons for each shift (8 hours). Plant (framework) proficiency is assessed at 50% of limit. (a) Determine the quantity of heaters required. (b) Estimate the percent of time the heaters will be inactive.
