4- The linear displacement of a vehicle due to an impact force is measured with a transducer. Transducer specifications are: Input range: Output range: Linearity: Drift: Repeatability: Sensitivity: 0 to 10 meters 0 to 10 volts ±0.25% reading ±0.25% /°C FSO ±0.25% reading ±0.10% FSO The transducer output is indicated on a voltmeter (accuracy: within ±0.1% of reading; Resolution: 10 μV). The expected nominal displacement of the vehicle is to be 4 meters for an impact force of 2200±100 N (95%). The force-displacement relation can be assumed linear. The test is conducted at an ambient temperature of 30 °C. Estimate a simple design-stage uncertainty analysis.
