If the Poisson’s ratio is given as 0.3 and the Young’s modulus is given to 7e10. What will be the value for shear modulus?

If the Poisson’s ratio is given as 0.3 and the Young’s modulus is given to 7e10. What will be the value for shear modulus? Correct Answer 2.69e10 N/m2

The relation between Young’s modulus, shear modulus and Poisson’s ratio are given by v = E/2G – 1. Taking the 1 on the left side and rearranging we get G = E/2(1+v). Inserting the values given in the question the answer comes out to be 2.69e10 N/m2. Here E = Young’s modulus, G = shear modulus and v = Poisson’s ratio.
