Hello :)
I have trouble understanding the characteristics of the links and understanding what is what (elastic or not, indirect or not, removable, etc.). Can you help me?
Thanks :)))

Hello!
The links have 4 main characteristics.
First, a link can be direct or indirect. It is direct if there is no connecting member between two parts and they fit together. A bond can also be indirect when it is accomplished through the help of an intermediary.
For example, the cap that screws onto a water bottle is an example of direct binding, while using glue to place a photo on a poster is indirect binding.
Then, a link can be rigid or elastic. If it is rigid, it is because it does not allow movement. The connection between a shelf and the wall is rigid.
The connection can also be elastic, so it allows movement between the assembled parts. This type of bond is often caused by an elastic connecting member or made of a flexible material. For example, the connection between the fabric of a trampoline and the structure which retains it is elastic, since the connection depends on springs.
The link can be removable or non-removable. It is removable if the parts can be separated without causing damage. For example, LEGO blocks form a removable link.
On the other hand, a non-removable link cannot see its parts come off without being damaged. For example, the link created by glue is often not removable, because its separation can break the assembled parts.
Finally, a link can be complete or partial. A link is complete if there is no degree of movement between the two assembled parts. For example, two bricks in a wall are linked by a complete bond.
On the other hand, a partial connection allows at least one movement between the parts. For example, scissors represent a partial link because the two parts can rotate around the screw that holds them in place.
Don't hesitate to ask other questions! :)
