Theory of Structures If E, N, K and 1/m are modulus of elasticity, modulus of rigidity. Bulk modulus and Poisson ratio of the material, the following relationship holds good E = 3K (1 – 2/m) All of these (3/2)K (1 – 2/m) = N (1 + 1/m) E = 2N (1 + 1/m) E = 3K (1 – 2/m) All of these (3/2)K (1 – 2/m) = N (1 + 1/m) E = 2N (1 + 1/m) ANSWER DOWNLOAD EXAMIANS APP
