1. Use suitable sketches to describe the principle of operation of a resistance strain gauge. 2. Calculate the strain experienced by a rođ of length 2m subjected to a force that causes a change of resistance of 0.2x 1012 in the gauge Wheatstone bridge circuit. The strain gauge has gauge factor of 1.5 and the resistivity of the Wheatstone bridge circuit wires is 1.83x10 ohm-meter having a cross-sectional area 0.03m² and length 0.15m.
