Beam Types

simply supported beam beam with a pin support at one end and a roller support at the other
cantilever beam beam that is fixed at one end and free at the other
beam with an overhang overhung portion is similar to cantilever beam, except rotation can occur at support

Pure Bending

uniform/pure bending

flexure of a beam under a constant bending moment (zero shear force, V = dM/dx)

 

nonuniform bending

flexure in the presence of shear forces (the bending moment changes as we move along the axis of the beam)
