14.30 (B). A certain equiangular strain gauge rosette is made up of three separate gauges. After it has been installed it is found that one of the gauges has, in error, been taken from an odd batch; its gauge factor is 2.0, that of the other two being 2.2. As the three gauges appear identical it is impossible to say which is the rogue and it is decided to proceed with the test. The following strain readings are obtained using a gauge factor setting on the strain gauge equipment of 2.2: Gauge direction 0° 60° 120° Strain x 10-6 +1 -250 + 200 Taking into account the various gauge factor values evaluate the greatest possible shear stress value these readings can represent. For the specimen material E = 207 GN/m2 and v = 0.3. [City U.] [44 MN/m².]
