Theory of Structures If Q is load factor, S is shape factor and F is factor of safety in elastic design, the following: Q = F – S Q = S + F Q = S × F Q = S – F Q = F – S Q = S + F Q = S × F Q = S – F ANSWER DOWNLOAD EXAMIANS APP
Theory of Structures A simply supported uniform rectangular bar breadth b, depth d and length L carries an isolated load W at its mid-span. The same bar experiences an extension e under same tensile load. The ratio of the maximum deflection to the elongation, is L/d (L/2d)² (L/3d)² L/2d L/d (L/2d)² (L/3d)² L/2d ANSWER DOWNLOAD EXAMIANS APP
