FUNDAMENTALS OF MECHANICAL VIBRATION

GUYS HERE I PRESENT YOU MY LITTLE EFFORT;

I have made a simplified easily understable ppt and has uploaded it on slideshare for your help 

ABOUT THE PPT

It is made to understand the basic definitions and terms used in mechanical vibration which is one of very important subject of MECHANICAL ENGINEERING and GATE so to have a quick look you should go through this slides but go through this slides only for a quick revision this is not meant for building up your concepts from ground level for that i would recommend you go through some good books

WHAT IS ABRASIVE GRADE/GRIT SIZE ?

GRIT SIZE
"The grit size indicate the abrasive grade on the abrasive side of paper."

It follows inverse relation with size of abrasive grain
i.e a higher grit number a smaller abrasive grain and vice versa

A “P” in front of the grit size indicates that the product is graded in accordance with the European FEPA standard

USE OF TERMS COARSE,MEDIUM AND FINE
This terms are used in conjugation with the Grit size of abrasive.
