WebHow can we measure the strain developed in a body? Let's look at a bunch of nuts and bolts that are falling under gravity. When they hit a rigid surface a small amount of strain is developed at the point of impact. This strain becomes negligible as we move away from the point of impact. 00:00 00:15 WebStrain is the deformation of a material from stress. It is simply a ratio of the change in length to the original length.
