(Edit: title should be 'Moving mass of lift increases exponentially)

Hi all,

I need some help understanding something, but to give you some quick background I am doing a final project on my access course at college on how tall can you build a skyscraper.

A problem engineers face is the issue of the elevator where the steel cable becomes too heavy as you get to 500 metres. I have read the moving mass increases exponentially, but how does it not increase proportionally? Double the distance/length of cable should surely mean the mass be twice as much.

The website here talks about it

https://www.google.co.uk/search?q=elevator+mass+increasing+exponentially&prmd=inv&ei=_zJqWOP-LIj_swGo_6TACA&start=10&sa

Could some help me with the mathematics please?. I have an A-level in maths so I understand exponential functions and equations.

Thanks
