Beam:
What do you mean by Beam, and Shear force and bending moment diagrams?
Sol.: A beam is structural member whose longitudinal dimensions (that is width) is large compared to the transverse dimension (that is depth). The beam is supported along the length of it and is acted by system of loads at right angles to the axis of it. Because of external loads and couples, shear force and bending moment develop at the section of beams. For the design of beam, information about shear force and bending moment is required.
