Levers Worksheet by toontownlady · Ninja Plans - Free Printable

Let me work through this step by step.

The task asks to identify the class of lever for each picture and label where the fulcrum, effort, and load are located.

Let me identify each image:
1. Scissors (top left)
2. Wheelbarrow (top middle)
3. Seesaw with two people (top right)
4. Pliers/wire cutters (bottom left)
5. Fishing rod (bottom middle)
6. Nutcracker or similar tool being held (bottom right)

Now let me classify each lever:

Class 1 Lever: Fulcrum is between the effort and the load
- Examples: seesaw, scissors, pliers

Class 2 Lever: Load is between the fulcrum and the effort
- Examples: wheelbarrow, nutcracker

Class 3 Lever: Effort is between the fulcrum and the load
- Examples: fishing rod, tweezers, human arm

Let me analyze each:

1. Scissors: The pivot point (fulcrum) is in the middle, the handles are where you apply effort, and the blades cut the load. This is a Class 1 lever.

2. Wheelbarrow: The wheel is the fulcrum at the front, the load (rocks/dirt) is in the middle of the barrow, and the person applies effort at the handles at the back. This is a Class 2 lever.

3. Seesaw: The fulcrum is in the middle, and people sit on either end applying effort/load. This is a Class 1 lever.

4. Pliers/Wire cutters: The pivot is in the middle, handles are where effort is applied, and the jaws grip the load. This is a Class 1 lever.

5. Fishing rod: The hand holding the bottom of the rod is the fulcrum, the other hand applies effort in the middle, and the fish at the end is the load. This is a Class 3 lever.

6. Nutcracker (the tool being held with both hands): Looking at the image, it appears to be a nutcracker where the hinge/pivot is at one end, the nut (load) is in the middle, and the hands apply effort at the other end. This is a Class 2 lever.

Wait, let me reconsider the last image. It shows hands holding what appears to be a nutcracker or similar tool. In a typical nutcracker, the fulcrum is at the hinge end, the load (nut) is in the middle, and effort is applied at the handles. This makes it a Class 2 lever.

Let me verify my answers:
1. Scissors - Class 1 ✓
2. Wheelbarrow - Class 2 ✓
3. Seesaw - Class 1 ✓
4. Pliers - Class 1 ✓
5. Fishing rod - Class 3 ✓
6. Nutcracker - Class 2 ✓

For labeling fulcrum, effort, and load:
- Class 1: Fulcrum in middle, effort and load on opposite ends
- Class 2: Fulcrum at one end, load in middle, effort at other end
- Class 3: Fulcrum at one end, effort in middle, load at other end

Final Answer:
1. Scissors - Class 1 lever (fulcrum at pivot, effort at handles, load at blades)
2. Wheelbarrow - Class 2 lever (fulcrum at wheel, load in barrow, effort at handles)
3. Seesaw - Class 1 lever (fulcrum in center, effort and load on opposite ends)
4. Pliers - Class 1 lever (fulcrum at pivot, effort at handles, load at jaws)
5. Fishing rod - Class 3 lever (fulcrum at bottom hand, effort at upper hand, load at fish)
6. Nutcracker - Class 2 lever (fulcrum at hinge, load at nut, effort at handles)
