As shown below (Fig.1), A strain gage with gage factor of 2.02 is mounted on the bottom of a beam to measure the strain on the surface of the beam. The beam's Young's Modulus is 193 GPa. A wheatstone bridge circuit was constructed as sketched in Fig. 2. Al resistors including the gage itself is 1202. Supply voltage is 5.0 V DC. The bridge is initially balanced when there is no load (a). when a downward load is added, will...

A 120 Ω strain gauge with a gauge factor of 2 is mounted on a beam and connected in a Wheatstone bridge as shown in Figure Q1a. The bridge is powered by a 12 V DC supply in series with a 510 Ω resistance. The beam is subject to a tensile force, which produces an axial strain of 940 microstrain measured by the strain gauge .a) Under no strain, calculate the current in the strain gauge and the power dissipated by the...
