8. 7.1 Shear and Bending Moment in a Beam
Beams are structural members which are designed to support loadings applied perpendicular to their axes.
In general, beams are long straight bars having a constant cross-sectional area.
They are classified as to how they are supported. See page 345 for types of supports of beams.

9. Shear and Bending Moment in a Beam Contd.
The design of a beam requires the determination of the variation of the internal shear force, V and bending moment M acting at each point along the axis of the beam.

10. Example
Sketch the shear force and the bending moment diagrams for the beam shown below. Determine the maximum bending moment.
