    INTRODUCTION

    A strain gauge is a device used to measure

    the strain of an object.

    Invented by Edward E.

    Simmons and Aurthur C. Ruge in 1938.

    DEFINATION

    A strain gauge is an example of passive

    transducer that converts a mechanical

    displacement into a change of resistance.

    WORKING

    The resistance of strain gauge wire is

    directly proportional to the mechanical

    stress applied on it.
