4. To precisely measure the change in the electrical resistance of a strain gauge, we commonly use the Wheatstone bridge. 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...

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...

Problem #1 (35 pts.) A solid 5 cm by 5 cm square aluminum rod, with a 70 GPa modulus of elasticity, is stretched by an unknown axial load. The initial rod length is 1 m, and its final length (after applying the axial load) is 1.0005 m. Assume that a strain gauge (with a gauge factor of 2.2) is firmly affixed to the rod, its active axis aligned with the length of the rod. You may assume the strain gauge...

Figure 3 shows a schematic arrangement of an in-line tension meter, commonly used to sense the tension T across a cable. The cable is routed through three pulleys (P1, P2 and Ps). As shown in Figure 3, only one of the pulleys (P2) is attached to the free end of a cantilever beam, sensorized with a set of four strain gauges in a full Wheatstone electrical configuration. The other two pulleys (P and P3) are 2...
