Study Smart not Hard ! - Tips for your Exam Preparation

Lets be practical, We all know we have exams and we have no options to avoid it.
In last minute everyone will have panic and tension all over us. Here are the few tips and strategies to over come it. 


Lets sub divide the whole things into three parts : 

• Before Examination
• During Examination
• After Examination

DYNAMICS OF MACHINERY

TWO MARKS

UNIT-I

FORCE ANALYSIS

1. What is meant by Dynamics of Machinery?

            Dynamics of Machinery is the branch of mechanics of machines which deals with the forces and their effects while acting upon the parts of machinery which are in motion. i.e. system changes with time.

2. Define force?

            It is an action in the form of push or pull exerted by one body on another body. Force produces or tends to produce motion.

3. State Newton’s First law of motion?

            Every body continues in its state of rest or of its uniform motion in a straight line unless an external force acts on it.
