INTRODUCTION
WHY ARE WE GOING TO DISSCUSS ABOUT THIS CONCEPT?
As a mechanical and civil engineer, we always work with machines under Structural
loads or we will be going to design constructions with different types of supports
and beams. This is a basic concept for an engineer to be aware of to do all such
things. By the end of this concept we are expecting a student will be capable to
identify all the supports, beams and loads
INTRODUCTION
 WHAT IS MEANT BY A BEAM IN ENGINEERING?
A beam is a structural element which is capable of withstanding transverse loads.
Simply a beam transfers its applied loads to the supports
 WHAT IS MEANT BY A SUPPORT?
A support is an element which bears the weight of a beam and keeps it upright.
Simply we can say that it is a thing which keeps beam in Equilibrium.
 WHAT IS MEANT BY A LOAD?
A load in this concept refers to the forces acting on Structures. This is the reason
these can be also called as structural loads.
TYPES OF SUPPORTS
Basing on the concept how they are supporting the beam they are classified into 4 types
1. Fixed Support
2. Simple Support
3. Roller Support
4. Hinged Support
FIXED SUPPORT
This support keeps the end of the beam fixed, i.e. The beam end resists to take any
kind of translation or bending moment. In the below figures we are going to see how
this support will be.
SIMPLE SUPPORT
In this type of support, the beam is allowed to rest freely on a support as we can see
in the below fig and there by we can observe that the beam is free to move in any
direction and also to rotate about the support
ROLLER SUPPORT
A Roller support gives capability of movement to the respected beam connected to it
may be along normal to the guides or it can also rotate about the support as we can
see in below figures
HINGED SUPPORT
A Hinged support restricts the movement of the beam in any directions but it will
allow the beam to rotate about the support just like a door which is an best example
of hinged support
TYPES OF BEAMS
Basing on the concept how they are supported they are classified into 6 types
1. Fixed Beam
2. Cantilever Beams
3. Beam with one end hinged and other end roller
4. Simply Supported Beams
5. Over Hanging Beams
6. Continuous Beams
FIXED BEAM
A Beam which is having fixed supports on both of its ends, it is named as fixed
beams and we can see some animated and real examples of these kind of beams and
how they are restricting the movement of the beam
CANTILEVER BEAM
A Beam which having a fixed support on one end and other end is set free, it is
known as cantilever beam as we can see some best examples of cantilever beam
below
BEAM WITH ONE END HINGED AND OTHER END ROLLER
This beam has one of its end hinged and the other side of the beam is supported
with rollers. These kind of beams are capable to withstand loads in any direction.
Below we can see a conventional figure and a bridge having this kind of support
SIMPLY SUPPORTED BEAM
A Beam with simple supports exactly at two ends of the beam then it is called as
simply supported beam. In the real world people wont tend to design anything with
simple supports, but one of the ancient monument was built up by this concept
OVER HANGING BEAMS
These beams will also have supports but one end or both ends of the beam will be
having some extension after the supports as we can see in below figure.
Note: The supports can be roller ,simple or
any other.
CONTINUOUS BEAMS
It is a beam which carries more than two supports and some of the examples of
continuous beams are bridges which are shown below
TYPES OF LOADS
Basing on the action of the forces the loads are classified into 3 types
1. Point Load (or) Concentrated Load
2. Uniformly Distributed Load
3. Uniformly Varying Load
POINT LOAD (or) CONCENTRATED LOAD
When a load acts concentrated at a definite point then it is named as a concentrated
load or point load. We can see some best examples of point load in the below figures
UNIFORMLY DISTRIBUTED LOAD
A distributed load is a load which is spread on some length of a beam, i.e. The
reason it is measured in intensity with units Newton/meter. If the intensity is
constant along the length then it is named as uniformly distributed load
UNIFORMLY VARYING LOAD
Whenever the load distributed along the length of the beam varies in intensity
uniformly, according to some law. Then it is named as uniformly varying load and
we can see some conventional figures below which are representing uniformly
varying loads

This is the reason these can be also called as structural loads.
  • 6. TYPES OF SUPPORTS Basing on the concept how they are supporting the beam they are classified into 4 types 1. Fixed Support 2. Simple Support 3. Roller Support 4. Hinged Support
  • 7. FIXED SUPPORT This support keeps the end of the beam fixed, i.e. The beam end resists to take any kind of translation or bending moment. In the below figures we are going to see how this support will be.
  • 8. SIMPLE SUPPORT In this type of support, the beam is allowed to rest freely on a support as we can see in the below fig and there by we can observe that the beam is free to move in any direction and also to rotate about the support
  • 9. ROLLER SUPPORT A Roller support gives capability of movement to the respected beam connected to it may be along normal to the guides or it can also rotate about the support as we can see in below figures
  • 10. HINGED SUPPORT A Hinged support restricts the movement of the beam in any directions but it will allow the beam to rotate about the support just like a door which is an best example of hinged support
  • 11. TYPES OF BEAMS Basing on the concept how they are supported they are classified into 6 types 1. Fixed Beam 2. Cantilever Beams 3. Beam with one end hinged and other end roller 4. Simply Supported Beams 5. Over Hanging Beams 6. Continuous Beams
  • 12. FIXED BEAM A Beam which is having fixed supports on both of its ends, it is named as fixed beams and we can see some animated and real examples of these kind of beams and how they are restricting the movement of the beam
  • 13. CANTILEVER BEAM A Beam which having a fixed support on one end and other end is set free, it is known as cantilever beam as we can see some best examples of cantilever beam below
  • 14. BEAM WITH ONE END HINGED AND OTHER END ROLLER This beam has one of its end hinged and the other side of the beam is supported with rollers. These kind of beams are capable to withstand loads in any direction. Below we can see a conventional figure and a bridge having this kind of support
  • 15. SIMPLY SUPPORTED BEAM A Beam with simple supports exactly at two ends of the beam then it is called as simply supported beam. In the real world people wont tend to design anything with simple supports, but one of the ancient monument was built up by this concept
  • 16. OVER HANGING BEAMS These beams will also have supports but one end or both ends of the beam will be having some extension after the supports as we can see in below figure. Note: The supports can be roller ,simple or any other.
  • 17. CONTINUOUS BEAMS It is a beam which carries more than two supports and some of the examples of continuous beams are bridges which are shown below
  • 18. TYPES OF LOADS Basing on the action of the forces the loads are classified into 3 types 1. Point Load (or) Concentrated Load 2. Uniformly Distributed Load 3. Uniformly Varying Load
  • 19. POINT LOAD (or) CONCENTRATED LOAD When a load acts concentrated at a definite point then it is named as a concentrated load or point load. We can see some best examples of point load in the below figures
  • 20. UNIFORMLY DISTRIBUTED LOAD A distributed load is a load which is spread on some length of a beam, i.e. The reason it is measured in intensity with units Newton/meter. If the intensity is constant along the length then it is named as uniformly distributed load
  • 21. UNIFORMLY VARYING LOAD Whenever the load distributed along the length of the beam varies in intensity uniformly, according to some law. Then it is named as uniformly varying load and we can see some conventional figures below which are representing uniformly varying loads
