Explain why hot forging would be used to manufacture the shear pin. (3 marks)
--- 6 WORK AREA LINES (style=lined) ---
→ Hot forging creates components that exhibit superior strength compared to casting or machining methods.
→ This process enables the production of more intricate geometries while achieving an ideal combination of mechanical properties.
→ These properties include maximum yield strength, increased ductility, and reduced hardness.

The cross-section of an extruded aluminium alloy plank is shown.
Outline the steps of the extrusion process. (2 marks)
--- 7 WORK AREA LINES (style=lined) ---
The extruded aluminium plank is made by:
→ Heating an aluminium billet (heat > recrystallisation temperature).
→ Forcing the billet through a heated die to make the necessary cross-section.
