Brief description of Bridge

-
A bridge is a man made structure built to avoid physical obstacles without closing the way underneath such as a valley,  body of water, or road, for the purpose of providing passage over the obstacle, usually something that can be detrimental to cross otherwise.
Types of Bridges:-  There are basically five types of Bridges.

1:- Suspension Bridge
2:- Cable Stayed Bridge
3:- Beam Bridge
4:- Truss Bridge
5:- Arch Bridge
 
1:- Suspension Bridge:- A suspension bridge is one of the most popular bridge designs. It features a cable support system that distributes the weight of the bridge deck between the two towers. The tension forces in the cables are converted to compression forces in the piers that then extends all the way to the ground.


2:- Cable Stayed Bridge:- Basically cable stayed bridge is a bridge that consist of one or more than one pillar with cables supporting roadbed.


3:- Beam Bridge:-  A beam bridge consists of a horizontal slab supported at each end. Because all of the weight of the slab is transferred vertically to the support columns, the columns can be less massive than supports for arch or suspension bridges, which transfer part of the weight horizontally.


4:- Truss Bridge:-  Truss Bridge basically defined as a bridge which supported by Truss.


5:- Arch Bridge:- An arch bridge is a bridge which supported on abutments on both ends shaped as curved arch.

IMPORTANT MECHANICAL PROPERTIES OF MATERIALS

Important mechanical properties of materials:- ELASTICITY:-  In this property body regains completely its original shape & size then it is called perfectly elastic body. Elastic limit marks the partial break down of elasticity beyond which removal of load result in degree of permanent deformation. Steel, aluminium, copper, may be considered to be perfectly elastic within certain limit   ·      Plasticity:- The characteristics of material by which it undergoes inelastic strain beyond those at the elastic limit is known as plasticity.   This property is particularly useful in operation of pressing and forging. When large deformation occurs in a ductile material loaded in plastic region, the material is said to undergo plastic flow. Ductility:- It is the property of material in which a material can be drown out longitudinally to a reduced section, under the action of tensile force.   A ductile material must possess a high degree of plasticity and strength. Ductile

  The volume of one 50 kg bag of cement is 34.5 litres   About 19 litres (38%) of water is required to hydrate 50 kg cement in sealed container.   The ordinary Portland cement when tested for its compressive strength at 28 days   according to the method describe by the standard specification, yields a minimum compressive strength of 43N/mm2 is called 43 grade  cement . Too fine cement is susceptible to air set and deteriorates earlier.   The setting time of cement can be controlled by varying the quantity of gypsum in cement. Sometime with the addition of water to cement, a premature set occurs within 5 minutes. This is called false set an is due to  the presence of anhydrous gypsum which is formed due to grinding of gypsum with too hot clinker .this is not to be worried .continuous mixing aggregates , cement and water will break the false set without  harming any property of the concrete .  The ability of cement to maintain a constant volume is known as soundness of cement. The abilit
