Review Questions

• How does the composition of steel contribute to its properties compared to pure iron?
  • The addition of carbon to iron transforms it into steel, significantly enhancing its strength and durability. While pure iron is relatively soft and malleable, steel's unique structure allows it to withstand greater stress and impact. This property makes steel far superior for construction and industrial applications where strength is critical.
• Discuss the environmental impact of steel production and how it has influenced modern manufacturing practices.
  • Steel production has traditionally been associated with high levels of carbon emissions due to the processes involved in smelting iron ore. This environmental concern has prompted manufacturers to seek more sustainable practices, including increasing the use of recycled materials in steel production. Innovations like electric arc furnaces are gaining traction as they utilize scrap steel and reduce energy consumption while lowering emissions.
• Evaluate the role of steel in installation art and how its characteristics influence artistic expression.
  • Steel plays a significant role in installation art due to its strength, durability, and versatility. Artists utilize its properties to create large-scale structures that can endure outdoor environments or dynamic interactions. The ability to manipulate steel through welding or forging allows for intricate designs that convey meaning or provoke thought, showing how material choice can deeply affect both form and function in art.
