Gearling — Wheels, Axles & Gears Gear Gatehouse

Hi!

I'm Gearling.

Welcome to Gear Gatehouse!

Will you help me investigate wheels, axles & gears?

The Grumblies have mixed up our clues.

Let's check the evidence!

A wheel and axle are connected rotating parts of different sizes.

They can transfer motion and provide force-distance advantages depending on the use.

How do directly meshing gears turn here?

  • A. In opposite directions
  • B. Always in the same direction
  • C. Both always stop

The answer is A: In opposite directions

Gears are toothed rotating parts that transfer motion.

Two directly meshing gears turn in opposite directions in a simple model.

That clue helps us make sense of this place.

Gears are toothed rotating parts that transfer motion.

Two directly meshing gears turn in opposite directions in a simple model.

If A turns clockwise, how does B turn?

  • A. Clockwise
  • B. Neither can move
  • C. Counterclockwise

The answer is C: Counterclockwise

Our diagram has Gear A touching Gear B.

If A turns clockwise, B turns counterclockwise.

Gears connect to wheel-and-axle mechanisms

rather than adding a seventh traditional simple-machine category.

Hmm...

how does that connect to our first clue?

Our diagram has Gear A touching Gear B.

If A turns clockwise, B turns counterclockwise.

Gears connect to wheel-and-axle mechanisms

rather than adding a seventh traditional simple-machine category.

What connects a wheel and its axle in this model?

  • A. No physical connection
  • B. Shared rotation
  • C. Only their paint color

The answer is B: Shared rotation

A wheel and axle are connected rotating parts of different sizes.

They can transfer motion and provide force-distance advantages depending on the use.

Nice investigating!
