The One Chain That Decides It All: Can You Guess Which Breaks to Make the Brick Fall?

At first glance, this puzzle looks straightforward: a wooden beam extends from a central post, with a brick resting on one side. Three chains—A, B, and C—support the beam. Yet only one of these chains, when removed, will cause the brick to fall. Which one is it? Before scrolling further, take a moment to form your own hypothesis. Is it chain A, B, or C?

Common Mistakes and Why Small Details Matter

Assuming All Chains Equally Bear the Load

It’s tempting to think each chain does the same job. In reality, the distribution of tension can vary significantly, and one chain might be carrying more crucial force than the others.

Overlooking the Role of Reaction Forces

This puzzle hinges on understanding how reaction forces keep the beam in place. Focusing only on the brick’s weight might lead you to the wrong chain.

Relying on Visual Symmetry

While chains A and B might look symmetrical, a closer look at the geometry and angles will reveal which chain is crucial for supporting the brick.

When you break down the forces involved, you’ll see that one chain is providing the key reaction force that prevents the beam from flipping.

Step-by-Step Guide to Solving the Puzzle

If you’re still not sure which chain is the culprit, follow these steps:

Identify the Main Support for the Brick

• The brick is on the right side, so whichever chain directly opposes the weight of the brick is essential to keeping it from tipping.

Visualize the Forces

• The beam exerts a downward force due to the weight of the brick.
• The chains each pull in different directions to balance this force.

Focus on the Reaction Force

• Among chains A, B, and C, only chain B is positioned in such a way that it directly counteracts the beam’s tendency to rotate or flip back when the brick’s weight pulls down.

Remove the Chain in Question

• If you remove chain B, the beam can pivot upwards on the left side (due to the tension from chain A and/or C).

• With no counteracting force on the right side, the brick will no longer be supported and will fall.

Answer: Chain B is the one that, if broken, makes the brick fall. By removing this critical reaction force, the beam flips back and the brick is no longer supported.

Conclusion

Were you able to guess correctly from the start? If so, give yourself a pat on the back—and if not, no worries! This puzzle is a perfect example of how small differences in positioning and angles can significantly impact the outcome.
