A force sensor with the static sensitivity 2.5 Ohms/N generates a change in resistance on its output. This sensor is placed in one arm of the deflection bridge with an input voltage of 9 V in order to measure this resistance change. With no force applied, the transducer’s resistance is 200 Ohms, and all resistances in the bridge’s arms are equal. (a) Draw the schematic diagram of the deflection bridge: (b) Calculate the output voltage of the bridge for forces...
