Gearling — Ramps, Wedges & Screws Screw Stair Tower

Hi!

I'm Gearling.

Welcome to Screw Stair Tower!

Will you help me investigate ramps, wedges & screws?

The Grumblies have mixed up our clues.

Let's check the evidence!

An inclined plane is a sloping surface.

A longer, gentler ramp can reduce ideal effort force by

increasing travel distance.

Which machine is a slope?

  • A. A fixed pulley only
  • B. A wheel's paint
  • C. Inclined plane

The answer is C: Inclined plane

An inclined plane is a sloping surface.

A longer, gentler ramp can reduce ideal effort force by

increasing travel distance.

That clue helps us make sense of this place.

A wedge applies forces as it moves between or into materials.

A screw is an inclined plane wrapped around a cylinder.

Which machine is a wrapped incline?

  • A. Pulley
  • B. Screw
  • C. Lever

The answer is B: Screw

A wedge applies forces as it moves between or into materials.

A screw is an inclined plane wrapped around a cylinder.

Hmm...

how does that connect to our first clue?

Our task cards match a ramp to raising cargo,

a wedge to splitting or separating,

and a screw to fastening through rotation.

These complete the six traditional machine types taught across the route.

Which tool type pushes materials apart in our example?

  • A. Wedge
  • B. An ordinary flat label
  • C. A color swatch

The answer is A: Wedge

A wedge applies forces as it moves between or into materials.

A screw is an inclined plane wrapped around a cylinder.

Nice investigating!
