A 1000N vertical force is applied to the crank of the same diameter as shown. The material specified for the crank is AISI 1035 HR steel. A factor of safety of 1.5 is specified for the design. Determine the minimum permissible safe diameter for the crank using the Von-Misses design theory. 200 mim diameter d 250 -100 mm 1000 N • Load Analysis • Stress Analysis Principal Stresses / Stress Element • Mohr Circle • Design Region/Equation • Material Properties
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.
