In today's article, we will be going to talk about the following topics:
➤ A simple definition
of statics and dynamics
➤ Examples of statics
and dynamics.
➤ Compare and contrast
statics and dynamics.
What is the simple definition of statics?
In engineering, the
simple definition of statics is the study of forces involving no movement. It
belongs to the field of mechanics in which an object does not change its
position.
In general, the
perception of statics is that an object is not subjected to changing its
position. In actuality, this is not always the case—a person sitting somewhere
for a long time is also an instance of statics.
What is the simple definition of dynamics?
Dynamic is the
opposite of static; it is related to the study of changeable motion and forces.
In mechanics, dynamics look at how a force moves an object. A moving vehicle is
an instance of dynamics.
Dynamics is further
categorized into two parts:
➤ Kinetics
➤ Kinematics
Kinetics in simple words:
Kinetics is a part of
dynamics that looks at the forces that make bodies movable.
Characteristics of Kinetics:
▸ Consideration of
force massively
▸ Investigation of the
factors that lead to motion.
Kinematics in simple words:
In contrast to
kinetic, kinematics, the branch of dynamics, identifies the motion of bodies
without considering the force liable for action. Apart from that, kinematics is
very advantageous in developing ideas for how mechanical systems should work.
It also assists in determining whether a design has the theoretical possibility
or complexities for the world.
Characteristics of Kinematics:
▸ Concern merely with
the position, acceleration, and speed of an object.
▸ Mass is not involved
in it.
▸ Consideration of
force is not involved.
▸ It is limited only to mechanics.
Compare and contrast statics and dynamics.
| Statics | Dynamics |
|---|---|
It deals with the
study of things that remain in a stationary position for an extended period. period of
time. |
It deals with the study
of things that are not in a stationary position but move. |
A person sitting, bridges, mobile towers, etc., are all
examples of statics. |
Moving
vehicles, aeroplanes, children playing see-saw, etc., are all examples of
dynamics. |
In
terms of engineers, Civil engineers have a significant concern with the
statics. As they work to build static objects like houses, buildings, roads,
etc., |
Mechanical
engineers have a significant role in dynamics as they manufacture moveable
things for the world. |
It has an acceleration
of zero. |
It does not have an acceleration
of zero. |
Static
possesses forward and backward force equally for which it has acceleration "0". |
Dynamic
does not possess forward and backward force equally. |
Formula:
F=ma |
Formula:
F=ma |
In this way, we discussed the definition, characteristics, examples and comparison and contrast of statics and dynamics.
