please help! You are using a half-bridge circuit to measure the strain on a beam. Both strain gages have nominal resistances of 120 Ω and strain gage factors of 1.92. The other two resistors used in the circuit have nominal resistances of 120 Ω An adjustable power supply is used to apply a 5.00 V source voltage to the bridge circuit. Prior to loading the beam, the bridge is initially balanced. a. If the beam experiences an axial strain of 380 microstrain, what output voltage do you expect from the bridge circuit? b. You perform the measurement and observe an output voltage of 4.1 mV from the bridge circuit. What is the axial strain on the beam in microstrain? Due to constraints with your digital multimeter (DMM) or DAQ unit, you need to increase the output voltage that you will see for a given amount of strain. What's the easiest thing c. you can do to accomplish this in your current bridge circuit setup? You are using a half-bridge circuit to measure the strain on a beam.
