Theory of Structures A load of 1960 N is raised at the end of a steel wire. The minimum diameter of the wire so that stress in the wire does not exceed 100 N/mm² is: 4.0 mm 5.5 mm 4.5 mm 5.0 mm 4.0 mm 5.5 mm 4.5 mm 5.0 mm 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 100 N/mm 2 80 N/mm² 120 N/mm² 150 N/mm² 100 N/mm 2 80 N/mm² 120 N/mm² 150 N/mm² ANSWER DOWNLOAD EXAMIANS APP

Theory of Structures A shaft is subjected to bending moment M and a torque T simultaneously. The ratio of the maximum bending stress to maximum shear stress developed in the shaft, is 2M/ T T/M 2T/M M/T 2M/ T T/M 2T/M M/T ANSWER DOWNLOAD EXAMIANS APP
Theory of Structures A short column (30 cm × 20 cm) carries a load P 1 at 4 cm on one side and another load P2at 8 cm on the other side along a principal section parallel to longer dimension. If the extreme intensity on either side is same, the ratio of P1 to P2 will be 2/3 8/5 5/8 3/2 2/3 8/5 5/8 3/2 ANSWER DOWNLOAD EXAMIANS APP
