Read the given statements and select which is/are correct.
A. Resistance strain gauges are very useful for measurement of tension, torque, force and stresses in structures.
B. Strain gauges are used in load cells and proving rings to measure force by the strain produced. .
-
A.
Both A and B
-
B.
Only B
-
C.
Only A
-
D.
Neither A nor B
Correct Answer:
A. Both A and B
Explanation:
Both statements A and B are correct. Resistance strain gauges are versatile sensors that convert mechanical deformation into electrical resistance changes, making them essential for measuring tension, torque, force, and structural stress. Furthermore, they are core components in transducers like load cells and proving rings, where they quantify applied force by detecting the resulting internal strain. Therefore, the correct option is Both A and B.
