Why do ball pens stop working after dropping onto the ground?

I just want to ask for some advice in order to repair mine

Maybe because the pen needs a continuous flow of ink between the tube and the ball, and this is disrupted by falling?

If it lands on the tip, socket holding the ball is pushed out of shape, so the ball will no longer roll.

Then, how to fix it?

I don't think it can be fixed.

no offense but biro ball point pens are very cheap few pennies each, why dont you just buy a new one?

Given how small the ball and socket are, you could technically repair them, but it would be too difficult to be worth the bother. Since, as 5614 pointed out, biros cost somewhere in the order of zero pence (or about 2 cents ) there's no real point, unless you're really attached to that pen (is it a really expensive one?).

 

 

When people die, they become biros.

LOL!

By the way, I want to browse some scientist answering web site, would you suggest some?

This one's alright: http://www.scienceforums.net

 

I suppose you could try http://physicsforums.com but it's much larger, so you might not get quite as much specialist attention. These forums are a good size though, without too many experts in one field, and the atmosphere is better, and it's *cough* well moderated. Since not everyone here is an expert in their field (or even in their field at all) the learning experience is pretty much shared, so you don't get a flat out answer or get demeaned if you disagree with/don't understand it.

Yeah, I totally agree, the bigger the forums are, the less attention people get! Its pretty good. A good number of members (even though some never come on!).
