A steel bar with modulus of elasticity 200 gpa and diameter 10 mm is loaded in tension with an axial load of 50 kN. If a strain gage of gage factor 2.115 and resistance 120 ohm is mounted on the bar in the axial direction, what is the change in resistance of the gage from the unloaded state to the strained state?
