**Beam**:-A
structural member which is acted upon by a system of external loads at right angles to its axis is known as beam.

**LOADING:-**It is a type of weight put on the beam
which causes the beam to deflect or bend in shape.

**TYPES OF BEAMS**:-There are five types of beams as under:-

1.**Cantilever Beam**:-A cantilever beam is one whose
one end is fixed and the other end carries a point or concentrated load or no point load or concentrated load

2. **Simply
Supported Beam**:-A simply supported beam is one which
carries two reaction forces at its two ends or a point load at its mid-point

3.**Overhanging
Beam**:-It
is a type of simply supported beam which overhangs from its supports.An
overhanging beam may overhang on one side only or on both sides of the supports.

4.** Rigidly
Fixed Or Built-In-Beam**:-It is a type of beam in which both
ends are fixed and carries a point load at its centre.

5. **Continuous
Beam**:-It
is a type of overhanging beam which consists of a numerous reaction forces and point loads.

A beam may be subjected to either or in combination of
the following types of loads:-

1.**Concentrated Or Point Load**:-It is a type of load which acts at the centre of the beam as shown below:-

2. **Uniformly
Distributed Load**:-It is a type of load which is
distributed uniformly over the entire length of the beam.

3. **Uniformly
Varying Load**:-These are the loads varying
uniformly from zero to a particular value and spread over a certain length of the beam.Such load is also called triangular load.
