The calibration of a spring balance is checked by applying a set of known masses to it, with the following results: Known input (g) 10 20 30 40 50 60 70 80 Output reading (g) 15.5 25.0 32.0 45.0 52.0 61.0 74.5 81.0 (a) Draw a graph by plotting the data points on the graph paper provided and draw a best-fit straight line through the data points. (b) Which of the following static measurement characteristics are evident in the input - output graph drawn: nonlinearity, dead space, sensitivity drift, threshold, zero drift, hysteresis? (c) Calculate the magnitude of the static measurement characteristics that you have just identified
