Explain why it is necessary to carryout frequency domain analysis of measurement systems? What are the two plots obtained when the frequency response of a system is carried out? A first order system when subjected to a step input has a temperature rise of 25oC after one hour and 37.5o after two hours starting from cold conditions. Calculate its final steady temperature rise and the thermal time constant. What is a strain gauge? Name four resistance materials for use in wire and foil gauges. What are the units for strain? Discuss the principle of operation of the strain gauge with relevant sketches. A resistance strain gauge with a gauge factor of 2 is fastened to a member, which is subjected to a strain of 1 X 10-6. If the original resistance value of the gauge is 130, calculate the change in resistance. Show how output voltage signals proportional to linear displacements imparted to the movable plate of a parallel plate capacitor. Discuss the problems encountered while measuring small displacements by capacitive transducers.
