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...

Consider the Wheatstone bridge shown below Derive the expression for Vo in terms of VEx, RI, R2, R3, and R4. Under what condition is the bridge balanced, that is, Vo 0 a. b. Let Resistor 2 represent a strain gauge, whose resistance changes from R2 to R2+ dR2. The resistances of all the other resistors stay fixed. This is called...

<Homework 04 P 2.106 - Enhanced - with Hints and Feedback Part A The Wheatstone bridge circuit configuration is often employed with strain gauges in measuring strains of beams and other mechanical structures. The four gauges are connected in a Wheatstone bridge as shown in the figure. The change in resistance is given by AR=RG AL in wich 4L is the strain for the surface of the beam to wich the gauge is attached, R, is the gauge resistance before...

EE 213: Linear Circuit Analysis Final Project Strain Gauge Amplifier A Force sensing strain gauge is rate at 2225 N. It is supplied by 11 V source and provides 3mV/V at the rated force. This means that the output of the staring gauge will be 33 mV if the force was 2225 N and -33 mV if the force was -2225N. Design an operation amplifier circuit to convert this voltage range from -33-33 mV to 0-3.3V. One terminal of the...
Problem 4 A generator with an internal resistance of RG = 1202 produces a 5us square pulse with an open-circuit voltage of Ve 5V.

Hi could you please provide how to do problem 2? 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...
