How does a Combination Lock work?

Описание: Ever wondered what’s actually happening inside a combination lock when you spin the dial? In this video, we take a detailed look at the inner mechanics of a classic three-number combination lock.
Using clear explanations and visual animations, this video breaks down how the dial, spindle, wheels, notches, lever, and shackle all work together to lock — and unlock — the device. You’ll learn why turning the dial in specific directions matters, how each number in the combination is mechanically set, and what finally causes the lock to open.
This is a step-by-step exploration of a clever mechanical system that’s been used for decades to keep things secure.

📌 In this video, you’ll learn:
The main parts of a combination lock
How the dial controls multiple internal wheels
Why direction changes are required
How the correct combination aligns the wheels
What actually releases the shackle

Perfect for students, engineers, makers, or anyone curious about how everyday objects work.
