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.

![Consider the thin (steel) plate in figure given below. The plate has a
uniform thickness t=1 cm., Young's modulus E= 25 x 10° N/cm?, and
weight density p= 0,2448 N/cm³. In addition to its self-weight, the plate
is subjected to a point load P = 200 N at its midpoint.
(Please be careful for the units.)
(a) Model the plate with two
finite elements.

(b) Write down expressions for
the element stiffness matrices and
18 cm
element body force vectors.
(c) Assemble the structural
stiffness matrix K and global load

vector F.
P =200N
(d) Using the elimination
approach, solve for the global
displacement vector Q.
(e) Evaluate the stresses in each
element.
