  • Have you ever wondered how different fluids flow? Why honey does not flow as easily as water?
  • Consider cornstarch and quicksand
  • What is stress?
  • It is because of viscosity! Viscosity is the resistance to flow, which relates to an even bigger concept known as momentum transfer.
  • Oblek is a mixture made out of cornstarch and water. This mixture acts like a solid and resists force.Quicksand, has a structure that becomes more viscous as the applied stress increases.
  • Stress encompasses the internal force exerted by neighboring particles on each other. The image above, has a knife spreading butter. Shear stress in being applied as the butter moves in parallel to the surface.
