Problem 6 (20 points): Strain gauges Gauge axis Tensile loading B a)

Problem 6 (20 points): Strain gauges Gauge axis Tensile loading B a) A strain gauge, having a gauge factor of 2, is mounted on a rectangular steel bar (E-200 GPa) as shown in the figure above. The bar is 3 cm wide, 1 cm high, and is subjected to a tensile force of 30 kN. Determine the resistance change of the strain gauge if the resistance of the gauge was 1202 in the absence of the axial load. (10 pts) AR = b) Assume that now the temperature causes some noise in the sensor and you have an additional strain gauge of same type for temperature compensation purposes. How would you integrate the additional sensor to the measurement system shown so that you can eliminate temperature effects? (10 pts)
