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 At any point of a beam, the section modulus may be obtained by dividing the moment of inertia of the section by Maximum tensile stress at the section Depth of the neutral axis Maximum compressive stress at the section Depth of the section Maximum tensile stress at the section Depth of the neutral axis Maximum compressive stress at the section Depth of the section ANSWER DOWNLOAD EXAMIANS APP
Theory of Structures If Q is load factor, S is shape factor and F is factor of safety in elastic design, the following: Q = S – F Q = F – S Q = S × F Q = S + F Q = S – F Q = F – S Q = S × F Q = S + F ANSWER DOWNLOAD EXAMIANS APP
