A strain gauge having a strain gauge factor of 2 is mounted on the top surface of a rectangular steel bar (Em = 200 GPa), as shown in the following figure. The bar is 20 mm wide and 10 mm high, and is subjected to tensile uniaxial force. If the resistance of the strain gauge in the absence of the tensile force was 100 2. Using a measuring device, the change in the resistance of the strain gauge after applying the tensile loading was found to be 0.2 2. _Gauge axis Tensile loading E, a. Calculate the tensile uniaxial loading value b. If the stated uncertainty of the change in resistance measuring device was +0.005 2 (95%) excluding the error in the resolution. If the devise resolution was 0.01 2. What uncertainty in the force would result when using this change in resistance measuring device?
