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.

Definition of energy method-The Energy Method is a general modeling technique, any multidisciplinary dynamic system can be captured by the Energy Method (kinetic energy, potential energy, work). Before diving into the energy method we should recall the definition of potential and kinetic.These are methods based on linear elastic behavior and conservation of energy, i.e. the work done by external forces equals the energy stored in the structure under load.
Advantage:
Energy methods are very useful for analysing structures, especially for those that cannot be analyzed by the application of the equations of statical equilibrium .
1) The energy methods have over virtual work is their application to the approximate solution of complex problems for which exact solutions may not exist.
