Mechanics -  it is the branch of engineering science which deals with the study of forces and effect of forces on the any bodies in rest or in motion Branches of mechanics on the basis of state of body- 1)Statics-  It deals with the study of forces and effects of forces on body when it is in rest   2)Dynamics- It is branch of mechanics which deals with study of forces and effects of forces on body when it is in motion   It is further divided into two branches  i)Kinetics- it is the branch of dynamics which deals with study of forces and effects of forces on body when it is in  motion  considering forces causing the motion ii)Kinematics- it is the branch of dynamics which deals with study of forces and effects of forces on body when it is in  motion without considering forces causing the motion Branch branches of mechanics based on the type of bodies  1)Engineering mechanics- engineering mechanics is that branch of engineering science which deals with the study of forces and

1)substructure (Foundation) - The lowest part of structure which is in direct contact with the ground and which  transmit  the  load of structure to the ground is known as Foundation or substructure  2) superstructure  -  The part  of structure  constructed above plinth  level is termed as superstructure plinth is the middle part of the structure

Different Building components are as follow 1)Foundation - It is the lowermost part of the Building which is below ground level and not visible.Its function is to transfer the load of building to transfer load of Building to the hard strata. 2)Plinth-  This is part of building just above the ground level. It's function is to raise floor level above surrounding soil so as to provide protection from rainwater and crawling animals and insects 3)Floor -  It is plane surface made up of tiles or special stones like granite or marble. 4)wall -  These are the members which determine the boundaries of the building and seperate the rooms. In load bearing structure walls carry load but in framed structure they act as a separator only. 5)Roof -  This is the top covering of Building. This may be flat or sloped the function of roof is to protect inside of Building from rain ,direct sunlight,  snow. 6)Windows  - These are the openings

Types of structures || Load bearing structure || Framed structure|| composite structure

Any building can be classified as a Load bearing structure or framed structure nowadays load bearing structure is almost obsolete  A) Load bearing structure  -  In load bearing structure walls are structural members and load of slab is carried by the walls and then walls transfer the load to foundation  Hence, below each wall , a foundation of increasing thikness is provided due to this the load is spread over larger area at the foundation level Advantage 1.Low cost Limitations of load bearing structure 1. Limited no. Of storeyes 3 to 4  2.Not suitable in earthquake prone areas  3.More thickness of wall so space is wasted 4.Takes more time for construction  5. Less durable B)Framed structure -  A frame made up of columns and Beams carries the weight of slab.The walls are only partition walls. The weight of wall is carried by the beam under it. Wall can not be built anywhere but only on top of beams. In framed structure load of slab is carried by beams and beams transfer tha
