# GATE 2021 CLASS HAND WRITTEN NOTES OF THEORY OF MACHINES AND VIBRATIONS In this blog, I will be telling all the Mechanical branch students how to prepare Theory of Machine and Vibrations(TOM) subject for GATE/IES.As all the mechanical branch aspirants will be aware that Theory of Machine and Vibrations(TOM) is one of the most important subject for mechanical branch. It is one of the core subjects and the concepts should be clear to prepare for other subjects as well.So, now question comes that how do you prepare it? What books to use? Which notes to be used? Which topic is most important ? I will be answering all these.From last year GATE papers :-

 YEAR 2020 2019 2018 2017 2016 2015 2014 Theory of Machine and Vibrations 8 10 8 8 8 12 13

The above table shows the marks distribution for GATE/IES paper. It can be seen that the range of marks for this subject varies from 8 to 13 average being 9.5 which is 9.5 % of total marks. Obviously, the marks distribution also shows, it is one of the most important subject who’s question are mostly easy and you can score 100% in  Theory of Machine and Vibrations(TOM).

## Books required for Theory of Machine and Vibrations preparation:-

1. Theory of machines    - by S.S Rattan

2. Theory of machines  - by Sadhu singh

3.Theory of machines and mechanisms  -   by John j .Uicker, Gorden               R.Pennock,   joseph E Shingley

Notes – by author [ME]  HAND WRITTEN MATERIALS.

## Topics :-

TOM:

1.Displacement, velocity and acceleration analysis of plane mechanisms

3.cams; gears and gear trains

4.flywheels and governors

5.balancing of reciprocating and rotating masses

6.gyroscope.

Vibrations:

1.Free and forced vibration of single degree of freedom systems, effect of damping;

2.Vibration isolation

3.Resonance

4.Critical speeds of shafts.

The all topic is important and you must solve more numericals in these topics.
