Write a detailed note on camshaft and follower? Uses and types of camshaft

CamCam 

is a rotating  element which gives its reciprocating or oscillating motion to another element which is called as followerCam

 follower:

A cam folloer is a machine part which recive rotating motion from cam. Follower is fitted vertical to the cam but we can use more then one follower according to our needs to get accurate motion from follower it is necessary for follower to touch with cam profile otherwise accurate motion cannot be recived. A spring is used to toch follower on the surface of cam

Uses of cam and follower :

Following are the uses of cam and follower Cam is mostly used in IC engine to drive inlet and outlet valves Cam is used to run machines on automatic feedCam is used for clamping in jigg and fixtures Cam is used in textile industry Cam Is used in automatic lathe feed mechanism

Types of cam

Following are the types of camCylindrical / barrel camRadial or disc camWedge type camFace cam

What is a flywheel? Material, Types, working, applications advantages and disadvantages

What is a flywheel?

Flywheel is a mechanical equipment that is used to store energy during an operation and then this energy is utilized for useful purposes in the machine during operation. Flywheel stores  energy in the form of kinetic energy. As you know "kinetic energy is the form of energy which is produced by the motion of an object"In case of a flywheel the kinetic energy is stored in flywheel by rotational motion of flywheel which is given by any primemover

Brinal hardness test is a type of Distructive test it is used to test the hardness of a machine. After tested of brinal hardness testing machine a machine part didn't remain useful anymore

Introduction of brinal hardness testing machine :

Brinal hardness testing machine

was invented by a swedish engineer (J. A Brinal) in 1900. A hardent steel ball indentor is used to test the hardness of any specimen.and if you needed to test the hardness of steel you have to use tungsten carbide ball indentor

Causes of more fuel consumption in boiler

Fuel consumption in boiler :

Fuel is used in boiler to increase the temperature of liquid which is being used to generate steam boiler fuel consumption play a very important role in the overall plan efficiency because if fuel consumption is increased on the same steam generation quantity this will increase the production cost of the boiler
