Steam Engine · World History

In the context of the Industrial Revolution, what does the 'sun and planet' gear system enable a steam engine to do?

  1. Calculate the movement of the stars
  2. Convert reciprocating (up-and-down) motion into rotary motion
  3. Regulate the temperature of the boiler automatically
  4. Distribute steam to multiple cylinders simultaneously
Show answer and explanation

Correct answer: Convert reciprocating (up-and-down) motion into rotary motion

Early engines were limited to pumping. By converting linear motion into circular motion, Watt's engine could drive rotating shafts, which was essential for powering the machinery in mills and factories.
