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 = S × F Q = S + F Q = F – S Q = S – F Q = S × F Q = S + F Q = F – S ANSWER DOWNLOAD EXAMIANS APP
Theory of Structures Pick up the correct statement from the following: In a loaded beam, the moment at which the first yield occurs is called yield moment In a loaded beam, the moment at which the entire section of the beam becomes fully plastic, is called plastic moment All of these In a fully plastic stage of the beam, the neutral axis divides the section in two sections of equal area In a loaded beam, the moment at which the first yield occurs is called yield moment In a loaded beam, the moment at which the entire section of the beam becomes fully plastic, is called plastic moment All of these In a fully plastic stage of the beam, the neutral axis divides the section in two sections of equal area ANSWER DOWNLOAD EXAMIANS APP
