The quantity "strain" expressed in terms of the fundamental quantities (mass, length, time) is equivelent to?
isn't this dimensionless?

Strain is equivalent to the amount of deformation or elongation experienced by a material when subjected to stress.
Strain is typically measured as a ratio of the change in length of a material to its original length, and is represented as a decimal or percentage.
Strain and stress are directly related, as strain is a result of the stress applied to a material. As stress increases, so does strain.
Yes, strain can be positive or negative depending on the direction of deformation. A positive strain indicates elongation, while a negative strain indicates compression.
Strain can significantly impact the behavior of materials, including their strength, elasticity, and ability to withstand stress. High strain can cause a material to permanently deform or even fracture.
