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) (3/2)K (1 – 2/m) = N (1 + 1/m) E = 2N (1 + 1/m) All of these E = 3K (1 – 2/m) (3/2)K (1 – 2/m) = N (1 + 1/m) E = 2N (1 + 1/m) All of these ANSWER DOWNLOAD EXAMIANS APP
Theory of Structures A steel rod of sectional area 250 sq. mm connects two parallel walls 5 m apart. The nuts at the ends were tightened when the rod was heated to 100°C. If steel = 0.000012/C°, Esteel = 0.2 MN/mm², the tensile force developed at a temperature of 50°C, is 150 N/mm² 120 N/mm² 80 N/mm² 100 N/mm 2 150 N/mm² 120 N/mm² 80 N/mm² 100 N/mm 2 ANSWER DOWNLOAD EXAMIANS APP
