1. The History of Mechanical Engineering

Ancient Foundations (Pre-1700s)

3000 BCE: Egyptians used levers and ramps to build pyramids.
1st Century CE: Hero of Alexandria invented the aeolipile (first steam engine).
Middle Ages: Windmills and water wheels revolutionized mechanical power.

Industrial Revolution (1700s-1800s)

1712: Thomas Newcomen built the first practical steam engine.
1781: James Watt improved steam engines, powering factories and trains.
1860s: Internal combustion engine emerged, leading to automobiles.

Modern Era (1900s-Present)

Early 1900s: Henry Ford’s assembly line revolutionized manufacturing.
1960s: NASA’s space missions advanced materials and thermodynamics.
2000s-Present: 3D printing, robotics, and renewable energy dominate innovations.

Today, Mechanical Engineers work on AI-driven automation, electric vehicles (EVs), and sustainable energy solutions.
