  • Watches

Step-by-step explanation:

Many devices and tools that you see or use daily are examples of repetivie motion:

Blenders:

  • the rotary movement of the blades of a blender is repetitive because it makes the same journey continuously.

Watches:

  • the clock hands repeat their movement throughout the day: the second hand every 60 seconds, the minute hand every 60 minutes, and the hour hand every 12 hours.

Hydrulic hammers

  • this tool drills holes or breaks rocks by knocking incessantly at an impressive rate: the tip goes down and goes up a large number of times per second.

Ball mills

  • ball mills grind by rolling the internal spheres over the materials that want to be crushed by continuously rotating the mill.

Electric saws

  • the sharp saw makes a continuos circular motion at high speed to cut the materials.
