Question # 1: (20min) Force TransductionA Resistive strain gauge (Resistance= 1Kohm; Gauge factor G=10) is used to measuremuscle force in the following experiment.1) Assuming the observed resistance change is 100 ohm, calculate the strain.2) The probe is placed into a bridge as shown below and amplified with a differentialamplifier (Ad=1000, CMRR=80dB). Calculate V+ and V- , Vd and Vc. Calculate the voltageoutput amplitude of the amplifier.3) Calculate the output voltage of the amplifier
