Beam: Beam is a horizontal structural member spacing and distance between one or more supports and carrying vertical loads across its longitudinal axis.
Types of bean:Beams are mainly of six types, which are given below.
1. Simply supported beam: In this type of beam supports act at the end of beam.
2. Cantilever beam: In the cantilever meam one end fixed and other end is free.
3. Overhanging beam: If the end portion of the beam is extended beyound the support such as a beam is known as overhanging beam.
4. Contineous beam: In this type of beam more than two supports act. Contineous beam is a longer beam.
5. Fixed beam: In this type of beam both ends are fixed.
6. Propped cantilever beam: In this type of beam one end fixed and other end roller support. It is used in bridges.
