A steel bar with modulus of elasticity 200 GPa and diameter 10 mm is loaded in tensionwith an axial load of 50 kN. If a strain gage of gage factor 2.115 and resistance 120 2 ismounted on the bar in the axial direction, what is the change in resistance of the gagefrom the unloaded state to the strained state? If the strain gage is placed in one branch ofa Wheatstone bridge (R1) with the other three legs having the same base resistance(R2=R3-R4=120 2), what is the output voltage of the bridge (Vout) in the strained state,as a function of the excitation voltage? What is the stress in the bar?Hint:PA =σ =ε =-=VeR₁R₂ex R₁+ R4 R₂+R3EBEAR =ЄFGR
