A strain gauge, having a gauge factor of 2, is mounted on a rectangular steel bar (E = 200. 10°KN/m”). The
bar is 3 cm wide and 1 cm high and is subjected a tensile force of 30 kN. Determine the resistance change of
the strain gauge if the resistance of the gauge was 120 2 in the absence of the axial load.
