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 + g/f)]/A [W (2 + f/G)]/A (1 – g/f)/A [W (1 + f/ G)]/ A [W (2 + 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 m = 3j – 2 j = 3m – 2 j = 2m – 3 m = 2j – 3 m = 3j – 2 j = 3m – 2 j = 2m – 3 ANSWER DOWNLOAD EXAMIANS APP
Theory of Structures Pick up the correct statement from the following: If tensile stress is equal to axial stress, the section experiences compressive stress If tensile stress is less than axial stress, the section experiences compressive stress All of these The moment of inertia is calculated about the axis about which bending takes place If tensile stress is equal to axial stress, the section experiences compressive stress If tensile stress is less than axial stress, the section experiences compressive stress All of these The moment of inertia is calculated about the axis about which bending takes place ANSWER DOWNLOAD EXAMIANS APP
