Normal Strain and Shear Strain - Strengths of Materials

Instagram:   / engineering_made_possible   This video goes over the concepts of Normal and Shear Strain and how they relate to stress. (0:00) Normal Strain (1:43) Normal Strain Equation (1:50) Stress vs Strain Relation (3:35) Problem statement: If the force P causes point A to be displaced 3mm, determine the normal strain in each wire. (7:57) Shear Strain (10:44) Problem statement: The rectangular plate was deformed into a parallelogram as shown here. Determine the shear strain at corners A and B.
