Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is a screw and how does it work?A screw is a helical shape that turns into a straight movement. When you twist it, the threads push it forward or pull it back. The distance between threads is called the pitch.
2. How does a screw lift heavy things?By turning, the screw moves slowly but pushes a load forward. A small twist can lift a big weight because the screw turns over a long distance. This gives a big mechanical advantage.

Inclined Plane: A fundamental simple machine consisting of a flat supporting surface tilted at an angle.
Mechanical Advantage: The ratio by which a machine multiplies the force or torque applied to it.
Pitch: The axial distance between adjacent threads on a screw or bolt.
Torque: A twisting force that tends to cause rotation.
