2. INTRODUCTION
Machines and mechanisms are essential components of
modern technology, enabling the efficient transfer of energy
and motion. Linkages, links, and joints are key elements in
the design of machines and mechanisms, providing the
necessary mobility and flexibility to perform specific tasks.
The four-bar linkage and slider crank mechanism are two
examples of common mechanisms that have a wide range
of applications in various industries.

3. TYPES OF MACHINES
• Simple Machines: These are basic
machines that have few or no moving
parts, such as levers, pulleys, and inclined
planes.
• Mechanisms: These are complex
machines that consist of multiple parts
that work together to perform a specific
task, such as linkages, gears, and cams.

Mobility in
Machines

5. Four-Bar Linkage
• A type of mechanical linkage
that is used to transfer
motion and force between
two objects.
• A four-bar linkage is a type
of mechanism that is used
to create motion in
machines. It consists of four
rigid links connected by
joints or pivots. Four-bar
linkages are used in a variety
of machines, including
engines, robots, and even
bicycles.

6. Slider-Crank Mechanism
• A type of mechanism that is
commonly used in internal
combustion engines to
convert linear motion into
rotational motion.
• The slider crank mechanism is
another important type of
mechanism that is used to
create motion in machines. It
consists of a slider, a crank,
and a connecting rod. Slider
crank mechanisms are used in
a variety of machines,
including engines, pumps,
and compressors.

7. Rocker-Bogie Suspension
System
A type of suspension system that
is used in Mars rovers to provide
stability and mobility over rough
terrain.

8. Scotch Yoke Mechanism
A type of mechanism that is
used in steam engines to convert
linear motion into rotational
motion.

9. CONCLUSION
In conclusion, machines and mechanisms are an
important part of our lives, and understanding the
components that make them work is essential for
engineers and designers. Linkages, links, joints, and
mobility are all important components of machines and
mechanisms, and four-bar linkages and slider crank
mechanisms are two important types of mechanisms
that are used to create motion in machines.
