Let's solve this step-by-step.
The worksheet asks you to
label each of the six simple machines shown in the images. Simple machines are basic mechanical devices that help make work easier by changing the direction or magnitude of a force. There are six classic simple machines:
1.
Lever
2.
Pulley
3.
Incline Plane (or Wedge)
4.
Wheel and Axle
5.
Screw
6.
Wedge
Now, let’s identify each one based on the diagrams:
---
1. Top Left Image:
- Shows a long board balanced on a triangular support (fulcrum), with a weight on one end and an arrow indicating downward force on the other.
- This is a
lever.
- A lever consists of a rigid bar that pivots around a fixed point (fulcrum).
✔ Label: *Lever*
---
2. Top Right Image:
- Shows a wheel with a rope wrapped around it, lifting a weight.
- This is a
pulley.
- A pulley uses a wheel and rope to change the direction of a force, often used for lifting.
✔ Label: *Pulley*
---
3. Middle Left Image:
- Shows a box placed on a sloped surface.
- This is an
inclined plane.
- An inclined plane is a flat surface set at an angle, used to raise objects more easily than lifting them straight up.
✔ Label: *Inclined Plane*
---
4. Middle Right Image:
- Shows a wheel attached to a central rod (axle).
- This is a
wheel and axle.
- The wheel turns around the axle, and together they reduce friction and allow movement.
✔ Label: *Wheel and Axle*
---
5. Bottom Left Image:
- Shows a screw with threads.
- This is a
screw.
- A screw is an inclined plane wrapped around a cylinder; it converts rotational motion into linear motion.
✔ Label: *Screw*
---
6. Bottom Right Image:
- Shows a diamond-shaped object (like a wedge).
- This is a
wedge.
- A wedge is a type of inclined plane that moves through a material, such as an axe or knife.
✔ Label: *Wedge*
---
Final Answer:
Label each image as follows:
1.
Lever
2.
Pulley
3.
Inclined Plane
4.
Wheel and Axle
5.
Screw
6.
Wedge
This completes the labeling of all six simple machines!
