Q. What is the working principle of mechanical comparators?

Answer

Here are the principles:Simply replace the plunger with the lever.There's a link between the lever and the seeing glass.The pivot holds the lever in place.Magnification is the product of the lengths L1 and L2. Therefore the L2 needs to be larger than the L1 in order to attain a higher magnification.The lever begins to revolve about its pivot as soon as the measurement point makes contact with the workpiece.When a user adjusts the mirror's tilt around the pivot point the reflection will change appropriately.An indication of the reading will be displayed on a graduated scale in the form of the reflected beam.
