Theory of Structures A two hinged parabolic arch of span l and rise h carries a load varying from zero at the left end to ? per unit run at the right end. The horizontal thrust is ωl²/8h ωl²/12h ωl²/4h ωl²/16h ωl²/8h ωl²/12h ωl²/4h ωl²/16h 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 400 mm 300 mm 200 mm 250 mm 400 mm 300 mm 200 mm 250 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 150 N/mm² 80 N/mm² 100 N/mm 2 120 N/mm² 150 N/mm² 80 N/mm² 100 N/mm 2 120 N/mm² ANSWER DOWNLOAD EXAMIANS APP
