# Introduction of Beam and Their Bending Moment

A beam is a horizontal member that is supported at its ends and is used to carry loads. The ends of the beam are called supports. The loads carried by the beam can be either point loads or distributed loads. The point loads are applied at the end of the beam, whereas the distributed loads are evenly distributed along the beam. The beam is subjected to bending moment when the loads are applied on it. The bending moment is the force that is exerted on the beam to make it bend. The amount of bending moment depends on the magnitude of the load, the distance between the load and the support, and the shape of the beam.

Beams are classified based on their shapes. The most common types of beams are rectangular

## Types of Beam and Their Bending Moment

• There are three types of beam and their bending moment.The first is the cantilever beam
• The cantilever beam has a horizontal force acting on it at one end, and a reaction force at the other end
• The bending moment is the force times the length of the beam.The second is the simple beam
• The simple beam has a vertical force acting on it at its center of gravity
• The bending moment is the force times the length of the beam.The third is the beam with a point load
• The beam with a point load has a force acting on it at its center of gravity, and a reaction force at the other end
• The bending moment is the force times the length of the beam.

## Types of Beam According to Support Condition

• There are three types of beams based on support conditions namely:
• Simply supported beam
• Cantilever beam
• Fixed beam
• A simply supported beam is one which is supported at its ends only
• A cantilever beam is one which is supported at one end only
• A fixed beam is one which is supported at both ends and is unable to move.

## Types of Beam According to Function and Position

• Types of Beam According to FunctionBeams can be categorized according to their function, which is determined by their position in a structure
• The three primary types of beams are load-bearing beams, horizontal beams, and Suspended beams.
• Load-bearing beams are responsible for supporting the weight of the structure above them, and are typically found in walls and columns
• Horizontal beams are used to provide support and stability for the structure as a whole, and are typically found in ceilings and roof trusses
• Suspended beams are used to support other beams and are typically found in Atriums and stairwells.
• Types of Beam According to PositionBeams can also be categorized according to their position in a structure
• The three primary types of beams are end beams, middle beams, and cantilevered beams.End beams are beams that are positioned at the ends of a structure
• Middle beams are beams that are positioned in the middle of a structure
• Cantilevered beams are beams that are positioned so that they project out from the side of a structure.

## Types of Beam According to Geometry and Shape

• There are several types of beams according to geometry and shape
• The most common shapes are rectangular, circular, and elliptical.Rectangular beams are the most common type of beam
• They are easy to construct and are very strong
• Circular beams are less common, but are often used in bridges and other structures where a lot of weight will be supported
• Elliptical beams are the least common type of beam
• They are very difficult to construct and are not as strong as rectangular or circular beams.

## Conclusion

Beams are one of the basic components in construction. They are used to support loads over long spans. The bending moment of a beam is the moment of the force exerted by the beam on the supported structure. The bending moment is a function of the length of the beam, the load on the beam, and the position of the load. The bending moment is maximum at the support and decreases as the load moves away from the support. The bending moment is zero at the center of the beam. The bending moment is negative at the end of the beam. The bending moment is a maximum at the support and a minimum at the end of the beam.
