Levers Worksheet - Free Printable

To solve this problem, we need to match each lever class diagram with the correct real-world example based on where the fulcrum (the pivot point), load (the weight being moved), and effort (the force you apply) are located.

Let’s go step by step:

---

Class One Lever:

In the diagram for Class One:
- The fulcrum is in the middle.
- The load is on one end.
- The effort is on the other end.

This is like a seesaw — fulcrum in center, load on one side, effort on the other.

Now look at the examples:
- Wheelbarrow → Fulcrum is at the wheel (one end), load in middle, effort at handles (other end) → That’s Class Two.
- Stapler → You press down on top (effort), staple comes out bottom (load), hinge is at back (fulcrum) → Effort and load on same side of fulcrum? Wait — actually, in a stapler, when you press down, the fulcrum is at the hinge (back), effort is applied near front top, load (staple) is pushed down at front bottom. So both effort and load are on same side of fulcrum → That’s Class Three? Not quite — let’s think again.

Actually, let’s use standard definitions:

✔ Class 1: Fulcrum between Load and Effort → e.g., scissors, seesaw, crowbar
✔ Class 2: Load between Fulcrum and Effort → e.g., wheelbarrow, nutcracker
✔ Class 3: Effort between Fulcrum and Load → e.g., tweezers, fishing rod, human arm

Wait — looking at the diagrams provided:

#### Diagram for Class One:
Load ———— Fulcrum ———— Effort
→ So fulcrum in middle → matches scissors? But wait — in scissors, each blade is a lever: fulcrum is the screw in middle, effort is your fingers on handles, load is what you’re cutting at tips → so yes, fulcrum between effort and load → Class 1.

But hold on — the image shows three examples: wheelbarrow, stapler, scissors.

Let’s assign correctly using standard knowledge:

🔹 Wheelbarrow:
- Fulcrum = wheel (at front)
- Load = stuff in barrow (in middle)
- Effort = you lifting handles (at back)
→ So: Fulcrum — Load — Effort → Class 2

🔹 Stapler:
When you press down:
- Fulcrum = hinge at back
- Effort = your hand pressing down near front top
- Load = staple being driven into paper at front bottom
→ So: Fulcrum — Effort — Load? Or Fulcrum — Load — Effort? Actually, since effort and load are both on same side of fulcrum, but effort is closer to fulcrum than load? No — in most staplers, you apply effort farther from fulcrum than the load (staple). Wait — actually, it's designed so that small movement of handle gives big force at staple. Typically, effort is applied between fulcrum and load? Let me double-check.

Actually, common classification:
- Stapler is often considered a Class 2 lever? No — wait, no.

Standard teaching:

✔ Scissors → Class 1 (fulcrum in middle, effort and load on ends)
✔ Wheelbarrow → Class 2 (load in middle, fulcrum at one end, effort at other)
✔ Stapler → Class 3? Or Class 2?

Wait — let’s look at the diagrams given in the worksheet:

The worksheet has labeled diagrams:

Class One diagram:
LOAD ———— ▲ (fulcrum) ———— EFFORT
→ So fulcrum between load and effort → This matches scissors

Class Two diagram:
▲ (fulcrum) ———— LOAD ———— EFFORT
→ Load between fulcrum and effort → This matches wheelbarrow

Class Three diagram:
LOAD ———— EFFORT ———— ▲ (fulcrum)
→ Effort between load and fulcrum → This matches stapler? Let’s see:

In a stapler:
- When you press down, the fulcrum is at the hinge (back)
- Your finger applies effort somewhere along the top (closer to front)
- The staple (load) is at the very front, below
So if fulcrum is at back, then moving forward: first you have effort (your finger), then load (staple)? That would be: Fulcrum — Effort — Load → which means effort is between fulcrum and load → that’s Class 3

Yes! So:

- Class 1: Fulcrum between load and effort → Scissors
- Class 2: Load between fulcrum and effort → Wheelbarrow
- Class 3: Effort between fulcrum and load → Stapler

But wait — in the worksheet, the images are placed next to each class, and we need to draw lines or match them.

Looking at the layout:

Left column: Class One, Class Two, Class Three with their diagrams
Right column: Images of wheelbarrow, stapler, scissors — each with a dot to connect.

We need to match:

→ Class One (fulcrum in middle) → should connect to scissors
→ Class Two (load in middle) → should connect to wheelbarrow
→ Class Three (effort in middle) → should connect to stapler

But let’s verify the stapler again.

Alternative way: Think about how you use them.

In a stapler:
- You push down on the top (effort)
- The staple goes down into paper (load)
- The hinge at the back is the fulcrum
So the order from back to front: Fulcrum (hinge) → Effort (where you press) → Load (staple exit) → So effort is between fulcrum and load → Class 3 ✔️

In wheelbarrow:
- Wheel (fulcrum) at front
- Load (dirt) in middle
- You lift handles (effort) at back
So: Fulcrum → Load → Effort → Load is between fulcrum and effort → Class 2 ✔️

In scissors:
- Screw (fulcrum) in middle
- Handles (effort) on one side
- Blades (load) on other side
→ Fulcrum between effort and load → Class 1 ✔️

Perfect.

So final matching:

- Class One → Scissors
- Class Two → Wheelbarrow
- Class Three → Stapler

But wait — in the image, the right-side items are listed as:

Top: wheelbarrow
Middle: stapler
Bottom: scissors

And left side:

Top: Class One
Middle: Class Two
Bottom: Class Three

So we need to draw lines:

Class One (top left) → connect to scissors (bottom right)
Class Two (middle left) → connect to wheelbarrow (top right)
Class Three (bottom left) → connect to stapler (middle right)

Yes.

Final Answer:

Class One → Scissors
Class Two → Wheelbarrow
Class Three → Stapler
