The whole idea of linear density makes no sense. There's no such thing as a "one dimensional object". —Preceding unsigned comment added by 98.173.141.129 (talk) 21:31, 9 July 2009 (UTC)Reply

comments on definition and the usage of one dimensional

edit

The applied definition:

 

is in my opinion wrong. It should read

 

where m is the mass of the element with length  

The idea of one dimensional must be specificed. A body can be considered as one-dimensional if

  1. the extend in space is in one direction much larger than in the other two directions
  2. changes of properties and dependant variables in the two short directions are small

The usage of one- and two-dimensional models is quite important in enineering and in former times in mathematics and physics. WE might consider to create an article for this item.

Notation for Linear Mass Density

edit

Should the first equation read  ? And the fourth read  ? Or is   a symbol for linear mass density? TryingMyBest (talk) 00:51, 23 February 2018 (UTC)Reply
