All four resistances when two strain gages mounted on a structure were measured to be 100 ohms with no load in a Wheatstone quarter bridge experiment. What are the changes in the resistances (in Ohms) corresponding to a tensile strain of 0.064 and a compressive strain of -0.0086 assuming a gage factor GF = 2.10? A. 0.1344 and 0.01806 B. 3.0476 and -0.409523 C. 13.44 and -1.806 D. 14.20 and 1.864
