Figure Q2 shows Cars A and B traveling around the circular race track. At the instant shown, A has a speed of 60 m/s and is increasing its speed at the rate of 15 m/s? until it travels for a distance of 100n m, after which it maintains a constant speed. Car B has a speed of 120 m/s and is decreasing its speed at 15 m/s? until it travels a distance of 65m m, after which it maintains a constant speed. a. Determine the constant speed achieved by cars A and B b. Determine the time taken for cars A and B to achieve constant speed c. Determine the time take for cars A and B to reach side by side
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.
