A resistance transducer has a resistance of 250 ohms and a gauge factor of 2.2. It is bonded to an object to detect movement.

Determine the change in resistance of the strain gauge, if it experiences a strain of due to the change in the size of the object.



What will be an ideal response?






Also, if the relationship between the change in the resistance and displacement is 0.05ohms per mm, determine the size of the object.
