Theory of Structures A composite beam is composed of two equal strips one of brass and other of steel. If the temperature is raised Steel experiences tensile force Composite beam gets subjected to a couple All of these Brass experiences compressive force Steel experiences tensile force Composite beam gets subjected to a couple All of these Brass experiences compressive force ANSWER DOWNLOAD EXAMIANS APP
Theory of Structures A simply supported rolled steel joist 8 m long carries a uniformly distributed load over it span so that the maximum bending stress is 75 N/mm². If the slope at the ends is 0.005 radian and the value of E = 0.2 × 106 N/mm², the depth of the joist, is 250 mm 400 mm 300 mm 200 mm 250 mm 400 mm 300 mm 200 mm 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 40 N 25 N 35 N 30 N 40 N 25 N 35 N 30 N ANSWER DOWNLOAD EXAMIANS APP
Theory of Structures The ratio of the length and depth of a simply supported rectangular beam which experiences maximum bending stress equal to tensile stress, due to same load at its mid span, is 1/4 1/2 2/3 1/3 1/4 1/2 2/3 1/3 ANSWER DOWNLOAD EXAMIANS APP
