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...

A Wheatstone bridge is comprised of 4 resistors, 120 Ohm nominal resistance each. Exactly one of these resistors (R3) is a strain gauge, gauge factor is 2.0. The supply voltage is 3 V. The bridge is in balance when the strain gauge is unloaded. Under loading, the strain gauge is subject to strain (epsilon=0.0025). In microstrain, the strain is Find the voltage output of the bridge in millivolts

Amsterdam University of Applied Sciences Problem 2(15 points) A Wheatstone bridge is used to determine the resistance of a strain gauge. The 3 resistances R of the Wheatstone bridge are equal: R 200 12. When the strain gauge is fully relaxed (nd strain present), its resistance Rs is equal to the other 3 resistances: Rs-R. The strain is given bywith AR, the change in resistance in the strain gauge. The...
