I concluded some time ago that mobile phones suck in general :P
But yes, some at least serve as a decent replacement for pocket cameras.
The correct answer to the quizz was 15 kN/m^2(I can only provide the german link). I couldn't find the specification of the lift's surface. But assuming a surface not less than 5 m^2 the lift can handle a weight of 7.5 t at least.
Interesting. I however have no clue whether this is a lot or not :)
PS: even if I can barely speak German, I can read it easily ;)
