it up).

Mechanical Functions
• Technical systems are made up of different
components.
• Each component in a system plays an
important role in the overall functioning of the
system.
• The role played by a component in a technical
system is called a mechanical function.
Basic Mechanical Functions
• There are 2 types of basic mechanical
functions:
–Links
–Guiding control
Links
A link connects, fastens, or puts together
two or more components of a technical
object.
Ex: nail, screw, nut, bolt, glue
Direct vs. Indirect Link
• The link between 2 components in a technical
system can be either direct or indirect.
• A direct link means that 2 parts connect to one
another WITHOUT a 3rd linking component.
• An indirect link means that there is a linking
component (glue, nail, screw, bolt, etc.) holding
the 2 components together.
Direct or indirect link?

Guiding Control
• Guidance is the function of a part that directs
another part along a specific path.
• Guidance dictates whether the motion is
either rotational or translational
Rotational or translational guide?
