  • Chemistry questions
  • This paper answers the following questions –

    1/ Explain the fundamental reasons why ceramics are brittle and metals are tough.

    2/ Explain why glass generally has low tensile strength and briefly describe two methods by which it can be ''strengthened''.

    3/Explain, in terms of Griffith's equation, why steel is a ''safer'' engineering materials than glass.


    4/ Explain the differences between elastic deformation, uniform plastic deformation and local plastic deformation (necking).

    5/ Describe the mechanism of rubber elasticity, explaining how it leads to low stiffness and high extensions.

    6/ Explain how the combination of thermosetting resin and glass fibres, both of which are brittle, gives composite materials which are tough.
