A 2.0-cm-diameter rod 50 cm long is subjected to an axial load and the strain measured with the bridge gage arrangement of Prob. 10.37. What axial force would be necessary to produce an axial deformation of 10 μm, and what would be the resulting gage reading in volts? Prob. 10.37 The bridge circuit of Prob. 10.36 is operated with a digital voltmeter having a very high input impedance. What voltage output will result from a strain of 3.1 μm/m? Prob. 10.36 A strain gage has a nominal resistance of 120 Ω. The gage is installed in a bridge circuit having equal arm resistances of 120 Ω and is operated as a current-sensitive device with a detector resistance of 350 Ω. The voltage source is 4.5 V. Calculate the current sensitivity of the device if the gage factor is 1.9.
