A resistive strain gauge, G = 2.1, is cemented on a rectangular steel bar, 4 cm wide and 1cm thick, with young modulus E = 200 × 106 kN/m2. An axial force F = 30 kN is applied. The change of the resistance of the strain gauge (ΔR) is ____ (in Ω), if the resistance of the unstressed strain gauge is R = 350 Ω.
