BEAM: A beam is structural element which has one dimension(length) consider larger than the other two dimensions (width,depth) and is supported a few points.
Types of Beams
1.Simply supported Beam
When both ends of beam are simply supported.It can support load in the direction normal to its axis.
2.Over-hanging Beam
If a beam is projecting beyond the support.
3.Cantilever Beam
If a beam is fixed at one end and is free at the other end.
4. Propped Beam
It is a beam with one end is fixed and other end simply supported.
5.Both Ends Hinged
These beams both ends swill be having hinged support.
6. Continuous Beam
It is supported at more than two points.
Types of Supports
1. Simple support
The beam in rest simply.In this case the reaction at the support is at right angles to the support and the beam is free to move in the direction of its axis.It is rotate about the support.
2.Roller support
The beam end is supported on rollers. The reaction is normal to the support since rollers treated as friction less. Many mechanical components are having roller supports which roll between guides.
3. Hinged support
A beam cannot move any direction in this beam. It can rotate about the support. The support will not develop any resisting mount. But it can develop support reaction in any direction to keep the end is stationary.
4.Fixed support
In this beam the end is not free to rotate or translate. But translation is prevented by develop reaction support in any direction.
Types of Loads
1. Concentrated Loads
If the load is acting on a beam over a very small length. It is approximately acting at the mid point.
2. Uniformly Distributed Loads(UDL)
This Loads has got uniform distributed for long distances. To find reaction the load may be assume to total load acts at the centre of gravity.
3.Uniformly Varying Loads(UVL)
This loads vary from long distances uniformly. The area of the triangle represents the total load and the centroid of the triangle represents the triangle centre of gravity of the load.
3.General Loads
The ordinate represents the intensity of loading and abscissa represents position of the load on the
4.External Loads
A beam may be subjected to "External moment at certain point".
