A strain gauge is used to measure the tension force in a 1-in. diameter bar of steel (E = 30, 000, 000 lb/ in?). The strain gauge has a nominal resistance of 140 N and a gauge factor (GF) of 4. The strain gauge is connected to a bridge (which is supplied with 10 Vdc). The bridge was initially balanced. After the bar is put under tension, the bridge output voltage goes to 0.0008 Vdc. Draw a schematic of the setup and calculate the force.
1) A compressive force is applied to a structural member. Two separate strain gauges are attached to the structural member; one is a nickel wire strain gauge having a gauge factor of -12.1 and the other is nichrome wire strain gauge having a gauge factor of 2. Calculate the value of resistance of the two gauges after they are strained, if the resistance of strain gauges before being strained is 120 2, and the compressive strain is 5 micro-strain. Assume positive value for tensile strain and negative for compressive strain. (Answer: For Nickel, R = 120.00726 Q. For Nichrome, R = 119.9988 Q)

A strain gauge is used to measure the tension force in a 2-cm diameter bar of steel with Young modulus of 2.07 x 107 N/cm2 (30 x 106 lb./in.2). The strain gauge has a nominal resistance of 160 Ω and a GF of 5. The gauge is connected to a bridge supplied with a 10 Vdc. The bridge was initially balanced.

QUESTION 2' a) When a strain gauge is stretched under axial tension, its resistance varies with the imposed strain. A resistance bridge circuit is used to convert the resistance change into voltage as shown in Figure 2. i) Distinguish among stress and strain. ii) In Figure 2, the 120 22 strain gauge with a gauge factor of 2 is mounted on a rectangular steel bar (Em = 200 GPa, 3 cm wide and 1 cm high) and connected to bridge circuit with input voltage, E₁=5 V. If the voltmeter shows 1.25 mV, calculate the amount of tensile load applied to the steel bar. Gauge axis Figure 2 E Tensile loading 3cm 1 cm
