Differences between direct stress and bending stress, Mechanical Engineering

Give differences between direct stress and bending stress.

Direct tensile and compressive stress is set up because of load applied parallel to length of object, and direct shear stress is set up in section which is parallel to line of action of the shear load. But bending stress is set up because of load at right angles to the length of object subjected to bending.

In the case of direct stress, nature and intensity of stress is same at any layer in section of object subjected to direct stress, but in the case of bending stress nature of stress is opposite on the opposite sides of neutral axis, and intensity of stress is differs at different layers of the section of object subjected to bending.

In the case of direct stress, intensity of stress is same in section taken through any point of object. But in the case of bending stress, intensity of stress is different at same layer of section taken through different points of object.
