ME 323. Mechanical Measurements (3-0-0-6)                                                     

Fundamental of Measurement: Elements of a generalized measurement system, standards, and types of signals; Static performance characteristics. Dynamic performance, instrument types – zero, first and second order instruments, transfer function representation, system response to standard input signals – step, ramp, impulse, and frequency response; Treatment of uncertainties: error classification, systematic and random errors, statistical analysis of data, propagation and expression of uncertainties; Measurement of various physical quantities: Linear and angular displacement, velocity, force, torque, strain, pressure, flow rate and temperature; Transfer functions of some standard measuring devices; Data Acquisition and processing: Digital methods, digitization, signal conditioning, interfacing, standard methods of data analysis – quantities obtainable from time series; Fourier spectra, DFT, FFT; Data acquisition parameters – sampling rate, Nyquist sampling frequency, aliasing & leakage errors; Metrology: measurement of angles, threads, surface finish, inspection of straightness, flatness and alignment, gear testing, digital readouts, coordinate measuring machine.
