Mechanical Measurements and Metrology

Mechanical Measurements and Metrology. Instructor: Prof. S. P. Venkateshan, Department of Mechanical Engineering, IIT Madras. This course discusses topics in mechanical measurements and metrology: errors in measurement, propagation of errors, regression analysis, measurement of field quantities like temperature and pressure, measurement of derived quantities like heat flux, measurement of thermo-physical properties, measurement of geometric forms and straightness, measurement of screw threads and gears, and measurement of surface roughness.
