QUESTION 1. a) Name the 6 families of engineering material, including relevant sub-categories (i.e. those depicted on Fig Q1) and characterize their typical Young's modulus. b) For each family of engineering material, clarify which exact 'strength' is associated with the material (eg: torsional strength, shear strength, etc...). c) For each family of engineering material, provide an example of a material with an application driven by its key properties (eg: Metals: Silver, used in mirror as one of the most reflective materials).
