A strip of steel sheet, 1.6 × 50 × 500 mm, is available for use as a forcemeasuring elastic element. The strip is to be used by cementing strain gages to its flat surfaces and measuring the deformation under load. The strain gages have a maximum strain of 2000 μm/m and a gage factor of 1.90. A battery is available with a voltage of 4.0 V, and the readout voltmeter has a high impedance and an accuracy of ±1 μV. The nominal resistance of the strain gages is 120 ? . Calculate the force range for which the measurement system may be applicable.
