Strain is equivelent to?

  1. Nov 13, 2006 #1
    The quantity "strain" expressed in terms of the fundamental quantities (mass, length, time) is equivelent to?


    isn't this dimensionless?

    Yes it is unitless! Strain doesn't have units -- it's the change in length per unit length.

    Absolutely. Use dimensional analysis if you have problems.
