2) One arm of a Wheatstone bridge is a 50 k2 strain gauge (S = 2.0)....
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...
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...
Question 2 Figure Q2 shows a strain gauge bonded to a piece of steel under a tensile force. The direction of strain measurement is at 90° to the direction of the force. The gauge has been selected to be self-compensating for temperature but the leads to and from the gauge are subject to temperature variations of 130 °C. The strain gauge and the metal have the following properties: Steel specification Gauge specification Gauge factor-2.00 Young's modulus -210 GN/m2 Poisson's ratio...
