Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the historical material evolution?Bronze (ancient Egypt) → Iron (Iron Age) → Steel (Industrial Revolution onwards)
2. What is the primary engineering function?Transmission of torque, lifting of loads, securing of objects, and conveying materials
3. Why do chains have oval or figure‑eight links?The oval shape lets the chain bend and fit around surfaces. This helps it move smoothly in machines like conveyors or hoists.
4. How do chains help in lifting heavy things?When weight is on a chain, the force spreads over many links so none break. This makes it safe to lift big loads with cranes or hoists.

Tensile Stress: The internal resistance of a material to being pulled apart by an external force.
Metallurgy: The science and technology of metals, including their extraction, processing, and properties.
Polymer: A large molecule composed of many repeating subunits, often forming long chains.
Blockchain: A decentralized, distributed ledger technology that records transactions across many computers.
