TYPES OF BEAMS & TYPES OF LOADINGS

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




BEAM









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

 
LOADING


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.     
         



                              2. Simply Supported Beam:-A simply supported beam is one which carries two reaction forces at its two ends & 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.




TYPES OF LOADINGS:-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.

I'm impressed. You're truly well informed and very intelligent. You wrote something that people could understand and made the subject intriguing for everyone. I'm saving this for future use.
