Question
Which simple machines make up scissors?
Answers

Scissors are made up of two primary simple machines: the lever and the wedge.
1. **Lever**: Each blade of the scissors acts as a lever. When you apply force to the handles, it causes the blades to pivot at the fulcrum (the point where the two blades are joined). This lever action allows the scissors to cut with relatively little effort.
2. **Wedge**: The edges of the blades are designed in such a way that they act as wedges when they come together. The sharp edges allow the blades to penetrate and cut through material by concentrating the force applied at the handles into a smaller area at the cutting edge.
Together, these two simple machines function to make scissors an effective cutting tool.
