1. Mechanical Engineering
Chapter 13
Mechanical Engineering
It is a branch of engineering that focus on the design, production and working of different technical objects.(p426)

2. LINKS
When an object has 2 or more parts then a link is needed to hold the two parts together.

3. Removable or Permanent Links
Links can be permanent that when you try to remove them they damage the object or they can be easily removable without any damage.

4. Complete or Partial Links
When the two objects can not move independently of each other then it is a complete link.
A partial link allows at least one part to move independently.

5. Direct or Indirect Links
When the link holds two parts together without any linking component that it is a direct link.
An indirect link needs a linking component between the two object.

6. Rigid or Flexible Links
A rigid link is a link that is not moveable, it is not flexible.
Springs and rubber are examples of flexible links.

7. GUIDING CONTROLS p
Translational guiding is when the motion is in one direction, up and down or left to right.

8. Rotational Guiding is when the motion is in a circle.

9. Helical guiding is when you have rotational and translational guiding.
