SUMMARY
The calculation of tensile stress using a strain gauge involves the unstrained resistance, gauge factor, and strained resistance. In this case, the unstrained resistance is 120 ohms, the gauge factor is 2.0, and the strained resistance is 120.13 ohms. The tensile stress can be calculated using the formula: σ = (ΔR/R0) * (GF * E), where ΔR is the change in resistance, R0 is the unstrained resistance, GF is the gauge factor, and E is the modulus of elasticity of the material. This method provides a precise way to determine tensile stress in materials subjected to strain.
