You have been asked to investigate two cooking surfaces, one made from spinel and one made from magnesia. In the tables at the end of this assignment you will find properties associated with these materials. a. How much would a 0.5 m diameter of each disk (assume isotropic) grow if heated from room temperature (22C) to 200C? b. Calculate the TSR for each and note which one would be less likely to break in this application. c. The magnesia disk is cooled from the melt at a moderate rate using a small amount of a nucleating agent, forming the final crystal structure. Thinking about this crystal structure, describe one way you could improve the thermal conductivity of the magnesia disk by changing this process and why this should work.
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.
