A composite beam is made of two brass (E = 107 GPa] plates bonded to an aluminum [E = 65 GPa] bar, as shown. The beam is subjected to a bending moment of 1890 N-m acting about the z axis. Assume b=59 mm, dq=49 mm, d2=10 mm. Determine: (a) the maximum bending stresses opr, Gal in the brass plates and the aluminum bar. (b) the stress in the brass oprj at the joints where the two materials are bonded together. Brass (2) dz Aluminum (1) Brass (2) dz Answers: (a) Obr = MPa, oal = i MPa. (b) obri = MPa.
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.
