In the resistance strain gauge arrangement of Fig. 4.72 strain gauge resistance R1=R2=R3=R4=
120ΩEb=9V. If the output voltage of the bridge is 20mV, find the value of force applied to the
strip. Thickness t of the strip =1mm. Width b of strip =10mm. Young’s modulus E of strip ma–
terial =8×1010Nm2. Length L=50mm. Strain at root of cantilever =6PLEbt2. Assume output
resistance as infinity. Gauge factor =2.4.
