1. Mechanical Functions

2. Class Starter
Give an example of a technical system and name some of it’s components (different parts that make it up).
__________________________________________________________________________________________
2) What would be the mechanical function of these different components?
3) What is a mechanical function?

3. 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.

4. Basic Mechanical Functions
There are 2 types of basic mechanical functions:
Links
Guiding control

5. Links
A link connects, fastens, or puts together two or more components of a technical object. Ex: nail, screw, nut, bolt, glue

6. 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.

7. Direct or indirect link?

8. 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

9. Rotational or translational guide?
