engineering recuitment UKPSC Polytechnic Lecturer Mock Test 2024 Strength of Materials Elastic Limit and Constants
Given below are the relations between the various elastic constants and Poisson's ratio. Identify the equation that is INCORRECT.
G: Modulus of Rigidity
μ: Poisson's Ratio
E: Young's Modulus
K: Bulk Modulus
1
G = E/(1 + 2μ)
2
K = E/3(1 - 2μ)
3
E = 9KG/(3K + G)
4
v = (3K - 2G)/2(3K + G)
