We were discussing various important topics based on
theÂ basics
of centrifugal compressorÂ andÂ hydraulic turbinesÂ in our
previous posts.Â

Today we will be interested here to start here a very
important subject i.e. engineering mechanics with the help of this post. We
will secure here the various principles and concepts of engineering mechanics
such as rigid and deformable bodies, basic concepts of force i.e. Concept of
force system in engineering mechanics, understanding of free body diagram,
equilibrium of forces and rigid bodies, basics of supports, basics aspects of
friction, basics of trusses etc.Â Â

So, let us start here first with the difference between
rigid and deformable bodies with the help of this post.Â

###
**Distinguish
between rigid and deformable bodiesÂ **

We are here to understand the very basic and important
concept of engineering mechanics i.e. difference between rigid and deformable
bodies.Â

###
**Rigid
bodyÂ **

Rigid body is basically defined as a body where
changes in the distance between any two of its points is negligible.Â

In case of rigid body, all the points will maintain
the same position with respect to another points and we may not change the
shape or deform the body by any way.Â

In practical, there is not a body of such type i.e.
perfectly rigid body and therefore this is only one idealization.Â

###
**Deformable
bodyÂ **

Deformable body is basically defined as a body where
changes in the distance between any two of its points could not be neglected.Â

In case of deformable body, all the points will not maintain
the same position with respect to another points and we may change the shape or
deform the body by applying the any kind of external force.Â

Therefore, we have seen here theÂ basicÂ difference between rigid and deformable bodiesÂ with the help of this
post.Â Â

Further we will see other various basic concept of
engineering mechanics such as concept
of force system,Â principle
of transmissibility of forcesÂ and its limitations,Â classification
of force system,Â body force and surface forceÂ in
mechanics.Â Â
