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 [W (2 + g/f)]/A (1 – g/f)/A [W (2 + f/G)]/A [W (1 + f/ G)]/ A [W (2 + g/f)]/A (1 – g/f)/A [W (2 + f/G)]/A ANSWER DOWNLOAD EXAMIANS APP
Theory of Structures A truss containing j joints and m members, will be a simple truss if m = 2j – 3 j = 2m – 3 m = 3j – 2 j = 3m – 2 m = 2j – 3 j = 2m – 3 m = 3j – 2 j = 3m – 2 ANSWER DOWNLOAD EXAMIANS APP
