Snapling — Magnetic Tools & Design Ironheart Vault
Hi!
I'm Snapling.
Welcome to Ironheart Vault!
Will you help me investigate magnetic tools & design?
The Grumblies have mixed up our clues.
Let's check the evidence!
Magnetic tools can sort materials, hold closures or lift suitable loads.
The best design depends on the material and task.
Which material can this tool recover?
- A. Every material in the mixture
- B. Iron pieces
- C. Every piece of plastic
The answer is B: Iron pieces
Our sorting tool attracts iron pieces from a mixture but leaves plastic.
A smaller working gap improves pickup in repeated model trials.
The final plan keeps the tested load and gap limits.
That clue helps us make sense of this place.
Tests should compare distance, load and other relevant conditions.
A successful trial has limits;
it does not establish unlimited strength.
Which change improved pickup in the record?
- A. A smaller gap
- B. A gap beyond all tested distances
- C. Changing only the label
The answer is A: A smaller gap
Our sorting tool attracts iron pieces from a mixture but leaves plastic.
A smaller working gap improves pickup in repeated model trials.
The final plan keeps the tested load and gap limits.
Hmm...
how does that connect to our first clue?
Our sorting tool attracts iron pieces from a mixture but leaves plastic.
A smaller working gap improves pickup in repeated model trials.
The final plan keeps the tested load and gap limits.
Why retain load limits?
- A. Magnetic tools have infinite strength
- B. Every magnet can lift every mass
- C. The evidence covers particular conditions
The answer is C: The evidence covers particular conditions
Tests should compare distance, load and other relevant conditions.
A successful trial has limits;
it does not establish unlimited strength.
Nice investigating!
