Stress, Strain, and Elastic Modulus (Part 2)

Bulk Stress, Strain, and Modulus. When you dive into water, you feel a force pressing on every part of your body from all directions. What you are experiencing then is bulk stress, or in other words, pressure.Bulk stress always tends to decrease the volume enclosed by the surface of a submerged object.

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.

12.4: Stress, Strain, and Elastic Modulus (Part 1)

A model of a rigid body is an idealized example of an object that does not deform under the actions of external forces. It is very useful when analyzing mechanical systems—and many physical objects are indeed rigid to a great extent.

Young''s modulus

Young''s modulus,, quantifies the relationship between tensile or compressive stress (force per unit area) and axial strain (proportional deformation) in the linear elastic region of a material: [2] = Young''s modulus is commonly measured in the International System of Units (SI) in multiples of the pascal (Pa) and common values are in the range of gigapascals (GPa).

11.1: Introduction to Chemical Equilibrium

Chemical change is one of the two central concepts of chemical science, the other being structure.The very origins of Chemistry itself are rooted in the observations of transformations such as the combustion of wood, the freezing of water, and the winning of metals from their ores that have always been a part of human experience.

What Is Young''s Modulus? Definition and Equation

Young''s modulus (E or Y) is a measure of a solid''s stiffness or resistance to elastic deformation under load. It relates stress (force per unit area) to strain (proportional deformation) along an axis or line.The basic principle is that a material undergoes elastic deformation when it is compressed or extended, returning to its original shape when the load is …
