Physics of Stress, Strain & Elasticity

In this physics lesson, determine the deformation of a particular quality by studying the forces inside the material and calculating the normal stress.

Discover how to measure and quantify the internal shear stresses, and the deformation that shear and normal stresses cause, also known as the strain.

In part 1 of this physics lesson, Moore Physics uses a rubber band experiment to investigate the relationship between stress and strain, or Young's modulus.

In part 2 of this physics lesson, Moore Physics continues demonstrating the calculations and equations for the rubber band experiment showing Young's modulus.

Discover how to use the modulus of elasticity to define the relationship of stress to strain without the constraints of Young's modulus in this physics lesson.
