Question

A voltage-excitation Wheatstone bridge will be used to measure the strain. The excitation voltage is Vin = 10 VDC, and the ballast resistors (resistors that are not strain gages) are assumed to have a fixed value of resistance R = 120 ohms, assumed exactly equal to unstrained gage resistance. The Wheatstone bridge can have many gage/resistor combinations, depending on where a gage is placed on the support rod and where it is connected to the bridge circuit.
