There's only so many ways things are attached together. Whenever you see a mechanical connection, try to find what assembly mechanism it uses!
- One piece, like a continuous block of steel.
- Soldered, brazed, or welded, like connecting copper to copper using molten-then-cooled tin-copper alloy.
- Adhered, like glue sticking paper to paper
- Fastened with thread, like with a machine screw or a bolt and nut.
- Pressure differential, like with suction cups.
- Plain contact, like a picture frame mounted on the head of a screw in the wall.
- Friction, like a semi-compressed spring holding itself inside a round tube.
- Weave, like a uniform cotton fabric pattern.
- Magnetic, like with 2 magnets attracting each other.
- Buoyant, like with a piece of wood floating on top of a tub of water.
- Gravity, like with a steel weight holding down a length of wire.
