Final answer:
An airplane capable of carrying 1,500 to 3,000 people is needed to meet the demand for increased passenger capacity.
Step-by-step explanation:
The need for an airplane that can carry 1,500 to 3,000 people arises from the demand for increased passenger capacity. It allows airlines to transport more passengers in a single flight, increasing efficiency and profitability. Additionally, such airplanes can also be used for special events or emergencies where large-scale transportation is required.
The material for the wings and body of the airplane should have certain properties to ensure safety and performance. It should be lightweight, yet strong and durable. This allows the airplane to achieve fuel efficiency and withstand the forces experienced during flight. Common materials used in aerospace engineering include aluminum alloys, carbon fiber composites, and titanium alloys.
Using very expensive new materials can lead to tradeoffs in terms of cost-effectiveness. While these materials may offer advantages like increased strength or reduced weight, they can significantly drive up the production cost of the airplane. This can make the resulting aircraft prohibitively expensive for airlines to acquire and maintain.
To improve an existing material, Charlia could focus on research and development efforts. This could involve testing and analyzing the material's properties, identifying its limitations, and finding ways to enhance its performance. Charlia may explore new manufacturing techniques, additives, or coatings that can improve the material's strength, durability, or other desired characteristics.
The material for the wings and body should be lightweight, strong, and durable. Expensive materials may offer advantages but can make the airplane too costly. To improve an existing material, Charlia can conduct research and development to enhance its properties.
