Homework Help: Strain is equivelent to?

    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.
