A load cell is a device which couverts a force or load into a more measureable output, such as voltage. You are required to design a load cell using two resistive strain gauges as the seasing elements (a) Draw an annotated diagram for the design and explain its working principle. (1) After realization of the design, the load cell is required to calibrate against a suitable standard. State the main objectives of calibration and describe the traceability chain of the load cell (C) The load cell is calibrated under the standard loading condition. The results are listed in Table Q4.
