Now that you understand forces, let’s observe various materials used in aerospace applications. Click on the tab labeled Materials. Metals Click on each material shown below and move the slider until the material cracks. Use the tick marks on the scale to assign a number to the force, cost and weight. Record this number on the following table. Move the slides completely to the maximum to see a message about the material. Complete the table below using what you learn. Type of Strength in Strength in Cost Weight Pros and Cons Applications Material Tension Compression (Stretching) (Squeezing) Aluminum -4 9 2 Pros;Lightweight, doesn't rust, strong in Airplane boats, cars, skyscraper "skin" compression and tension Cons; Expensive Cons: 4 Steel -3.5 6.8 9 Pros: One of strongest materials used in Cables in suspension bridges, trusses, beams construction, strong in compression and and columns in skyscrapers, roller coasters tension, 4 Cons: Rusts, loses strength in extremely high temperatures Based on your results, in which loading condition (tension or compression) are metals strongest? In compression aluminum is stronger but in tension is stronger Even though steel is an exceptionally strong metal, why wouldn’t it be a good choice for use inside jet engines? It is extremely heavy Polymers on the material shown below and move the slider until the material cracks. Use the tick marks on the scale to assign a number to the force, cost and weight. Record this number on the following table. Move the slides completely to the maximum to see a message about the material. Complete the table below using what you learn.
