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 2 120 N/mm² 80 N/mm² 150 N/mm² 100 N/mm 2 120 N/mm² 80 N/mm² 150 N/mm² ANSWER DOWNLOAD EXAMIANS APP
Theory of Structures A truss containing j joints and m members, will be a simple truss if m = 2j – 3 j = 3m – 2 m = 3j – 2 j = 2m – 3 m = 2j – 3 j = 3m – 2 m = 3j – 2 j = 2m – 3 ANSWER DOWNLOAD EXAMIANS APP
Theory of Structures A lift of weight W is lifted by a rope with an acceleration f. If the area of cross-section of the rope is A, the stress in the rope is [W (2 + f/G)]/A [W (2 + g/f)]/A (1 – g/f)/A [W (1 + f/ G)]/ A [W (2 + f/G)]/A [W (2 + g/f)]/A (1 – g/f)/A [W (1 + f/ G)]/ A ANSWER DOWNLOAD EXAMIANS APP
Theory of Structures A masonry dam (density = 20,000 N/m³) 6 m high, one metre wide at the top and 4 m wide at the base, has vertical water face. The minimum stress at the base of the dam when the reservoir is full, will be 75 N/m² 7500 N/m² 75000 N/m² 750 N/m² 75 N/m² 7500 N/m² 75000 N/m² 750 N/m² ANSWER DOWNLOAD EXAMIANS APP
Theory of Structures A steel bar 20 mm in diameter simply-supported at its ends over a total span of 40 cm carries a load at its centre.
