Youngs modulus of elasticity and Poissons ratio of a material are 1.25...
Modulus of Rigidity Calculation:
1. Given Values:
- Young's Modulus (E) = 1.25 x 10^2 MPa
- Poisson's Ratio (ν) = 0.34
2. Formula for Modulus of Rigidity (G):
G = E / (2 * (1 + ν))
3. Calculate Modulus of Rigidity:
G = 1.25 x 10^2 / (2 * (1 + 0.34))
G = 1.25 x 10^2 / (2 * 1.34)
G = 1.25 x 10^2 / 2.68
G ≈ 0.4664 MPa
Therefore, the Modulus of Rigidity of the material is approximately 0.4664 MPa, which corresponds to option (c).

Youngs modulus of elasticity and Poissons ratio of a material are 1.25...
As E = 2G(1 + μ)
1.25 x 102 = 2G(1 + 0.34)
G = 0.4664 x 102 MPa.
