Theory of Structures A steel bar 5 m × 50 mm is loaded with 250,000 N. If the modulus of elasticity of the material is 0.2 MN/mm² and Poisson’s ratio is 0.25, the change in the volume of the bar is: 2.125 cm³ 3.125 cm³ 4.125 cm² 1.125 cm³ 2.125 cm³ 3.125 cm³ 4.125 cm² 1.125 cm³ ANSWER DOWNLOAD EXAMIANS APP
Theory of Structures A spring of mean radius 40 mm contains 8 action coils of steel (N = 80000 N/mm²), 4 mm in diameter. The clearance between the coils being 1 mm when unloaded, the minimum compressive load to remove the clearance, is 30 N 35 N 40 N 25 N 30 N 35 N 40 N 25 N ANSWER DOWNLOAD EXAMIANS APP
