🔹 1. LEVER
-
What is a lever? A rigid bar that pivots around a fixed point (fulcrum) to lift or move objects.
-
Image: A seesaw-like setup with a suitcase (25 lb) on one side and a smaller weight (10 lb) on the other, balanced on a fulcrum.
-
Look at options:
- Scissors –

🔹 4. INCLINED PLANE
-
What is an inclined plane? A sloped surface that reduces effort needed to lift something.
-
Image: A ramp with a box being pushed up.
-
Options:
- Stairs –
Yes! Stairs are a series of small inclined planes.
- Wood lathe – Not related.
-
✔ Correct match: STAIRS
---
🔹 5. WEDGE
-
What is a wedge? A type of inclined plane that moves through material (like cutting or splitting).
-
Image: A wedge driving into wood.

🔹 6. WHEEL AND AXLE
-
What is a wheel and axle? A circular object (wheel) attached to a rod (axle); turns together to move or lift.
-
Image: A wheel and axle (like a spool).
-
Options:
- Hammer – Not a wheel and axle.
- Skateboard –
Yes! A skateboard has wheels attached to an axle (the trucks).
-
✔ Correct match: SKATEBOARD
