Week 19: Locking Mechanisms

Locks have been around for almost 6000 years! That means we still the same technology as ancient Egypt. But how does it work?

A pin tumbler lock, the key has a series of ridges that correspond to pins of different lengths within the lock cylinder. When the correct key is inserted, the pins are lifted to the correct height, allowing the lock to turn and the door to open. In a combination lock, a specific sequence of numbers or symbols must be dialed to align the internal components to release the locking mechanism.

Here are the parts you will need to design.

1. An outside lock cylinder body

2. An inside lock cylinder body

3. Lower Pins

4. Upper pins

(Refer to the diagram)

Here is my design in Fusion, but you can use Tinkercad as well.

Good Luck!
