Strain has units of inches per inch or millimeters per millimeter and hence is dimensionless. In most structures the values of strain are usually very small; for example, a low-strength steel will yield (take a permanent deformation) at a strain of only about 0.0014. As a result it is common to talk about strain in units of micro-strain ..

On September 13, 1848, the then 25-year-old Gage was working as the foreman of a crew preparing a railroad bed near Cavendish, Vermont. He was using an iron tamping rod to pack explosive powder into a hole. Unfortunately, the powder detonated, sending the 43 inch long and 1.25 inch diameter rod hurtling upward. The rod penetrated Gage's left cheek, tore through his brain, and exited his skull before reportedly landing some 80 feet away. . Though blinded in his left eye, he might not even have lost consciousness, and he remained savvy enough to tell a doctor that day, “Here is business enough for you.”.
