This video is for education purposes only and not for commercial use.

This is Part 2 for Chapter 6 on Mechanical Properties of Metals and Alloys

The chapter learning objectives are:

Define the Engineering Stress and engineering strain
State the Hooke's law and Poisson ratio and note the conditions which it is valid.
Given an engineering stress-strain diagram, determine (a) the
modulus of elasticity, (b) the tensile strength, and (d) estimate percent of elongation.
