Simple machines are basic mechanical devices that change the direction or magnitude of a force. Examples of simple machines include:
* Lever: A rigid bar that pivots around a fixed point (fulcrum) to multiply force.
* Wheel and axle: A wheel attached to a rod (axle) that helps move things or reduce friction.
* Pulley: A grooved wheel with a rope running over it to change the direction of force.
* Inclined plane: A flat surface at an angle to the horizontal, making it easier to move objects up.
* Wedge: A triangular tool used for splitting or separating objects.
* Screw: A spiral ridge wrapped around a shaft, used to fasten objects or move things.
A windshield is a structural component of a vehicle designed to protect passengers from the elements and debris. It doesn't have any moving parts or mechanisms that would classify it as a simple machine.
