Frequently asked questions
Divide the change in length by the original length. A 0.002 m stretch on a 2 m bar is a strain of 0.001.
Yes. It is a ratio of two lengths, so the units cancel, leaving a dimensionless number.
Stress is force per area; strain is the resulting deformation relative to original size.
Sometimes as a percentage or in microstrain (millionths), but the basic value is a simple ratio.
