BTec Engineering - Stress and Strain Graphs (PowerPoint)

This is an 8 slide PowerPoint that covers BTec National Engineering (A-Level equivalent) on the topic of Stress - Strain graphs, linking tensile stress and strain and the calculation of the modulus of elasticity
 
This is the third and final PowerPoint in this section which goes over some of the work from lesson one (Tensile stress and strain) and goes into more detail of graph analysis to find yield point, tensile strength as well as comparing qualitatively ideas like malleable and brittle materials.
