Describe the physical properties of the materials (permeability, capillarity and thermal conductivity) and explain how these properties are determined.
1) Draw (using a normal graph paper) a conventional
stress-strain diagram for ANY metallic material (e.g. steel,
aluminium, copper, brass, iron, tungsten). The diagram
should be as accurate as possible using a suitable scale
(e.g. 1cm: 10 N).
2) Calculate the Modulus of Elasticity, Modulus of
Toughness and Modulus of Resilience for the material
from the stress-strain diagram. Show your calculations in
detail on a separate A4 piece of paper.
Provide a concise explanation on how materials can exhibit high thermal conductivity but have low electrical conductivity.
