A strain gauge has a unstrained resistance of 120 ohms, guage factor of 2.0 is connected to steel girder so it experieces tensile stress. If strained resistance of gauge is 120.13 ohm. How do i calculate the tensile stress value?

I have looked all over the internet for equations relating but have not succeded, any help would be great
