Question
QI. A load cell uses a strain gauge of R-1202 GF-2.02 mounted on an aluminum column of 15 cm diameter to measure weigh of objects. a) Find the change in resistance per kg placed on the column. Is this change an increase or decrease in resistance? b) Draw a diagram of the system showing how active and dummy gauges should be mounted. c) Show how to add another active gauge and dummy gauge to the system to provide increased sensitivity. d) Assume a bridge excitation of 5.0 volts; determine the bridge deflection voltage per 500 kg placed on the column. Note: The stress is uniaxial and the transversal strain is negligible. Aluminum constant E-6.89x10" N/m i only need part d pls
