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 (1 + f/ G)]/ A (1 – g/f)/A [W (2 + f/G)]/A [W (2 + g/f)]/A [W (1 + f/ G)]/ A (1 – g/f)/A [W (2 + f/G)]/A [W (2 + g/f)]/A ANSWER DOWNLOAD EXAMIANS APP
