HEAT TRANSFER

MODES OF HEAT TRANSFR :
There are three modes of heat transfer
1.CONDUCTION
2.CONVECTION
3.RADIARION

 CONDUCTION :- In this mode ,heat transfer from one part to another part of opaque solid without appreciable displacment of the particles.
Conduction involves the transfer of kinetic energy from one moleculer to an adjacent molecular.
It is the only mechanism of heat flow in an opaque solid .
Conduction always requires a material medium.

FRICTION

WHAT IS FRICTION ?  Friction is a force wich oppose motion of a body. It always act in opposite to the direction of movement. TYPES OF FRICTION : SLIDING FRICTION:-   It is the the friction,experienced by a body ,when it  slides over another body. ROLLING FRICTION:-  It is the friction,experienced  between the surfaces whuch has balls or roller interposed between them. PIVOT FRICTION :- It is the friction ,experienced by a body due to the motion of rotation as in case of foot step bearings. BOUNDARY FRICTION /GREASY FRICTION / SKIN FRICTION/NON VISCOUS FRICTION :- When the two surfaces in contact have a very thin layer of lubricant between them,it is known as Boundry friction. The thickness of this vry thin layer is of the molecular dimension.

CASTING

Q. WHAT IS CASTING ? ANS- Casting is a very important manufacturing process. It is used to produce any product as a single unit. *  In casting ,metal is first  melted with the help of a suitable furnace.Then the metal is poured     in a cavity similar to the size of object being made.where it is lefted to solidify.After   solidification the cavity is destroyed to take out the solid object from it.  The solid object as well   as the process are called casting.
