UNIT-I 1.1 Standards of Measurement Total views (11)  
Metrology is a science of measurement. Metrology may be divided depending upon the quantity under consideration into: metrology of length, metrology of time etc. Depending upon the field of application it is divided into industrial metrology, medical metrology etc. Engineering metrology is restricted to the measurement of length, angles and other quantities which are expressed in linear or ang ......

UNIT-2 2.1 COMPARATORS AND ANGULAR MEASUREMENT Total views (1)  
Comparators can give precision measurements, with consistent accuracy by eliminating human error. They are employed to find out, by how much the dimensions of the given component differ from that of a known datum. If the indicated difference is small, a suitable magnification device is selected to obtain the desired accuracy of measurements. It is an indirect type of instrument and used for li ......

UNIT-3 3.1 MEASUREMENTS AND MEASUREMENT SYSTEMS Total views (0)  
The Measurement is the process of comparing quantitatively an unknown magnitude with a predefined standard. Standard is defined as “something that is set up and established by authority as a rule for the measurement of a quantity, weight, value or quality”. Example: A meter is standard established by an S.I (System International) organization for measure length. A measurement system is based o ......

UNIT-4 4.1 MEASUREMENT OF FORCE, TORQUE AND PRESSURE Total views (2)  
Introduction to Force Force represents the mechanical quantity which changes or tends to change the relative motion or shape of the body on which it acts. Force is vector quantity specified completely by its magnitude, point of application, line of action and direction. The relationship between motion and force is provided by the laws of dynamics. Newton’s second low of motion states that for ......
