Theory of Structures There are two hinged semicircular arches A, B and C of radii 5 m, 7.5 m and 10 m respectively and each carries a concentrated load W at their crowns. The horizontal thrust at their supports will be in the ratio of None of these 2 : 1½ : 1 1 : 1½ : 2 1 : 1 : 2 None of these 2 : 1½ : 1 1 : 1½ : 2 1 : 1 : 2 ANSWER DOWNLOAD EXAMIANS APP
Theory of Structures A simply supported beam carries varying load from zero at one end and w at the other end. If the length of the beam is a, the maximum bending moment will be wa/27 wa²/27 wa² w²a wa/27 wa²/27 wa² w²a 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 80 N/mm² 150 N/mm² 100 N/mm 2 120 N/mm² 80 N/mm² 150 N/mm² 100 N/mm 2 120 N/mm² ANSWER DOWNLOAD EXAMIANS APP
