In the resistance strain gauge arrangement of Fig. 4.1 strain gauge resistance R1 = R2 = R3 = R4= 120 Ω Eb = 9 V. If the output voltage of the bridge is 20 mV, find the value of force applied to the strip. Thickness t of the strip = 1 mm. Width b of strip = 10 mm. Young's modulus E of strip material = 8 x 1010 N/m2. Length L = 50 mm. Strain at root of cantilever = 6PL/Ebt2. Assume output resistance as infinity. Gauge factor = 2.4.

In the resistance strain gauge arrangement of Fig. 4.1 strain gauge resistance R1 = R2 = R3 = R4= 120
Ω Eb = 9 V. If the output voltage of the bridge is 20 mV, find the value of force applied to the strip.
Thickness t of the strip = 1 mm. Width b of strip = 10 mm. Young’s modulus E of strip material = 8 x
1010 N/m2. Length L = 50 mm. Strain at root of cantilever = 6PL/Ebt2. Assume output resistance as
infinity. Gauge factor = 2.4.
