Loading of Structures

Body structure are under considerable load. This loading results in development of substantial stress and strain Depending on the point of load, there is tensile load on one side and compressive load on the other side. 

Axial load: applied parallel to the longitudinal axis of the structure. This type of load can be either tensile or compressive. 

Torsional load: also known as torque. It is a rotatory load applied by force couple that tends to twist the structure. 

Bending moment (M): If a load is applied to a structure a distance away from the long axis, the effect is to bend the structure. This load creates a bending moment. 

Cantilever bending: a special type of bending load where load is applied to a structure at its free end perpendicular to the long axis and the structure is fixed at other end. Maximum bending moment would occur at the fixed end. Best example is a man standing on the end of a diving board.Amount of bending moment varies along the length of the board and is equal to the product of
