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 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 (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 [W (2 + f/G)]/A [W (2 + g/f)]/A ANSWER DOWNLOAD EXAMIANS APP
