There is no such thing as a Stupid Question!

Don't be embarrassed of your curiosity; everyone has questions that they may feel uncomfortable asking certain people, so this place gives you a nice area not to be judged about asking it. Everyone here is willing to help.

ex. How do I change oil
ex. How to tie shoes
ex. Can you cry underwater?

Reminder that the rules for lemmy.ca still apply!

Thanks for reading all of this, even if you didn't read all of this, and your eye started somewhere else, have a watermelon slice 🍉.

Mechanical fuse. Typically composed of shear pins or can be geartrain shafts manufactured with intentionally thinner cross-sections placed at strategic points. A plastic cog in some power tools serves a similar purpose.
