Types of beam
Simply supported beam:-
A beam supported freely on the walls or columns at its 
both ends is known as simply supported beam.
Over hanging beam:-
A Beam is freely supported on two supports. But its 
one end or both the ends are projected beyond the 
support.

as cantilever Beam.
Fixed Beam:-
A beam whose both ends are rigidly fixed is known as 
cantilever beam.

Type of loads
Point load or concentrated load:-
When  a load is acting on a relatively small area it is 
considered as point load or concentrated load.
W = Point Load
It is given in N or KN.
