12.4: Stress, Strain, and Elastic Modulus (Part 1)
Tensile or Compressive Stress, Strain, and Young's Modulus. Tension or compression occurs when two antiparallel forces of equal magnitude act on an object along only one of its dimensions, in such a way that the object does not move. One way to envision such a situation is illustrated in Figure (PageIndex{1}).
