Understanding Stress and Strain in Mechanics

The video tutorial explains the concepts of stress and strain using a tug of war analogy. Stress is defined as the internal resistance of a material to external forces, measured in pascals or psi. Strain is the deformation caused by stress, calculated as the change in length over the original length. The tutorial covers uniaxial loading, tensile and compressive stress, and the units used to measure stress. It emphasizes the importance of understanding these concepts to predict material performance and prevent failure.
