Joining Technology
A joint is any place on a structure where pieces are held together.
1. Joints are important for many reasons:
2. Allow the use of multiple materials
3. Allow a structure to have different components
o Without joints, a structure would have to be carved or mold “Mobile Joints” are joints that allow movement.
-->Your shoulder is a ball and socket joint
• “Rigid Joints” prevent movement.
-->A stool has a rigid joint between the
seat and legs
•Your task for today is to read a section of text and make a note with the title
"Joining Methods"
•In your note, you should cover the following topics, including a brief explanation and example of each:
o Mobile vs Rigid Joints
o Fasteners
o Ties
o Adhesives
o Melting
o Interlocking Shapes
•Joints are normally the weakest point
of structure, therefore there is a
need for a variety of
types of joints to suit a variety of different situations.
