Are You Ready For Introduction Of Engineering Mechanics (part-1)

Hello guys, today we are going to discuss about the Basic introduction of the engineering mechanics So guys, Let’s start

ENGINEERING MECHANICS:

The subject of Engineering Mechanics is that branch of Applied Science, which deals with the laws and principles of Mechanics, along with their applications to engineering problems. As a matter of fact, knowledge of Engineering Mechanics is very essential for an engineer in planning, designing and construction of his various types of structures and machines

DIVISIONS OF ENGINEERING MECHANICS:

The subject of Engineering Mechanics may be divided into the following two main groups:

 1. Static

 2. Dynamics.

STATICS:

It is that branch of Engineering Mechanics, which deals with the forces and their effects, while acting upon the bodies at rest.

DYNAMICS:

It is that branch of Engineering Mechanics, which deals with the forces and their effects, while acting upon the bodies in motion

The subject of Dynamics may be further sub-divided into the following two branches:

1. Kinetics

2. Kinematics

KINETICS:

It is the branch of Dynamics, which deals with the bodies in motion due to the application of forces

KINEMATICS:

It is that branch of Dynamics, which deals with the bodies in motion, without any reference to the forces which are responsible for the motion.

FUNDAMENTAL UNITS:

The measurement of physical quantities is one of the most important operations in engineering. Every quantity is measured in terms of some arbitrary, but internationally accepted units, called fundamental units. All the physical quantities, met with in Engineering Mechanics, are expressed in terms of three fundamental quantities, i.e.

1. Length,  

2.  Mass  

3.  Time.

DERIVED UNITS:

Sometimes, the units are also expressed in other units (which are derived from fundamental units) known as derived units e.g. units of area, velocity, acceleration, pressure etc.

SYSTEMS OF UNITS:

There are only four systems of units, which are commonly used and universally recognised. These are known as:

1. C.G.S. units,   

2.  F.P.S. units,     

3.  M.K.S. units

4.  S.I. units
