Worked Solution & Example Answer:Explain the term non-ferrous and name one non-ferrous metal - Leaving Cert Engineering - Question Question (g), (h), (i) - 2022
Step 1
Explain the term non-ferrous and name one non-ferrous metal.
Answer
The term non-ferrous refers to metals that do not contain significant amounts of iron. This distinction is important because non-ferrous metals generally have different properties compared to ferrous metals, such as better resistance to corrosion and lighter weight. An example of a non-ferrous metal is aluminium.
Step 2
State one reason why aluminium may be used when manufacturing satellites for use in space.
Answer
One reason why aluminium is used in the manufacturing of satellites is that it is a light material and will not corrode. Its low weight helps in minimizing the overall mass of the satellite, which is critical for launch and maneuverability in space.
Step 3
Describe the main operating features of any one of the following:
Answer
To address this part, I will describe the main operating features of satellites.
-
Communication: Satellites are often equipped with transponders that facilitate communication signals between the ground and other satellites. This allows for various applications such as telecommunication, broadcasting, and internet services.
-
Data Collection: Many satellites are designed to collect and transmit data regarding weather patterns, environmental changes, and research data, aiding in scientific studies and disaster management.
-
Navigation: GPS satellites provide precise location data to users on Earth, enabling navigation for personal and commercial use.
-
Surveillance: Some satellites are used for reconnaissance and surveillance purposes, assisting military operations and monitoring global security.
