The question is: "A rope has tensile Young's modulus of 0.64 GPa and a breaking strain of 0.021.

The rope is 50m long and has a diameter of 0.015m. What is the maximum tensile force that can be applied to the rope before it breaks in N?"

My answer was wrong, and I don't know where to go from here.

This is my working out, there is an 'X' next to the wrong answer: https://imgur.com/a/zdDCkez

Is the breaking strain not tensile strain? If so, what is it? Or maybe the F= tensile stress x A is not the one to use?

Thanks for any help
