Question: A Wheatstone Dodge was initially balanced with four equal resistances of 240 Ω, as shown in Fig. 1. The input voltage to the bridge s 24 V. The gage factor for each of the strain gages is 2.08. During flight testing. a strain gage sensor is located at R4. If the aerodynamics applied to the flying wing changes the resistance le.4 and the bodge output Ms Is measured at 1.2 V.

(a) Find the aerodynamic strain of the test specimen on sensor R4?

(b) How much current flows through the strain gage sensor R4?

(c) Hem much power mint be dissipated?
