What is LVDT? An LVDT (linear variable differential transformer) is an electromechanical sensor used to convert mechanical motion or vibration into a variable electrical current, voltage or electric signals, and vice versa.  Us ed to measure the displacement- As the primary is connected to an AC source so alternating curren…

Transducer A transducer is an electronic device that converts energy from one form to another.  The physical quantity which is to be measured can be pressure, level, temperature, displacement, etc. The output which is obtained from the transducer is in the electrical form and is equivalent to the measured quantity. Parts of tr…

Gear A gear is a toothed cylindrical or roller shape component of a machine which meshes with another toothed cylindrical to transmit power from one shaft to another. It is mainly used to change in torque and speed of the driving shaft and the driven shaft. Principle of gear It works on the basic principle that energy is n…

Mechanical engineering  is a discipline of  engineering  that applies the principles of physics and materials science for analysis, design, manufacturing, and maintenance of  mechanical  systems. Mechanical engineering courses develop your ability to design and create mechanical systems, including those used in the  automotive…

Hot working process It is a process in which the material is heated above its re-crystallization temperature but below the melting temperature of the material. less amount of power is required for deforming the metal in hot working as compared to cold working. Re-crystallization temperature of Fe= 450°c But the melting tempe…
