Case Study - Material Selection Problem: Select suitable material for bicycle frame and fork. Steel and alloys Low cost but heavy. Less Corrosion Resistance. Wood Light and strong. But not green.

Carbon fiber Reinforced plastic Very light and strong. No corrosion. Aluminum alloys Ti and Mg alloys Light, moderately Slightly better Strong. Corrosion Resistant. Than Al alloys. Discuss the deciding factors in selecting materials for a bicycle.
