When answering the following questions , ensure that you explain in terms of both the microscopic and macroscopic structure of the materials. A) polymer - explain the difference in structure between a thermoplastic and thermoset material and explain how the structure accounts for the key generic properties of those polymers. B) composite material - for a particular composite and a fibre reinforce composite , explain the difference in structure and whst structual features dictate the properties of the material.

To select a material for an application, it is necessary to evaluate whether its chemical and mechanical structure can be applied to a specific function and whether its properties will meet the required demands of the applied product. One way to identify these characteristics is to understand the types of deformations that materials can undergo.
Describe the differences between elastic deformation and plastic deformation in polymers, and how these concepts influence the mechanical properties of polymeric materials. Then, provide examples of practical situations where each type of deformation can be observed.

- QUESTION 1 (a) Powder Metallurgy (PM) enables the processing of materials with very high melting points, including refractory metals such as tungsten, molybdenum and tantalum. Such metals are very difficult to produce by melting and casting and are often very brittle in the cast state. As a manufacturing engineer, state and explain at least SIX (6) limitations of powder metallurgy that is not applicable in particular engineering industries. In a case where you were assigned to use powder metallurgy in metal forming, justify at least THREE (3) PM requirements. (b) A coil of sheet metal is placed in a furnace and annealed in order to improve its ductility. Nonetheless, it is found that the sheet metal has a lower limiting drawing (LDR) than it had before the annealing process.
