1. See-saw: A see-saw is a common playground equipment that consists of a board balanced on a central fulcrum. When one person sits on one end of the board and pushes off the ground, the lever action causes the other end of the board to lift them up.
2. Nail remover: A nail remover is a tool with a flat, narrow head that is wedged under the head of a nail. By applying force to the handle of the nail remover, the lever action helps pry the nail out of the surface it is driven into.

1. Flagpole: A flagpole often has a pulley at the top to raise and lower the flag. The pulley consists of a wheel with a groove for the rope to run through, allowing the flag to be easily hoisted up and lowered down.
2. Clothesline: A clothesline typically has multiple pulleys installed along its length to help easily hang and take down clothes. The pulleys reduce friction and make it easier to move the clothesline in order to hang more clothes without much effort.

1. Bicycle: The wheel and axle on a bicycle are essential components that allow the rider to move forward with ease. The axle is the rod that connects the wheels, which rotate around the axle when pedaled. This rotation provides motion and allows the rider to move the bicycle forward.
2. Door knob: A door knob often functions as a wheel and axle mechanism, where the knob acts as the wheel that turns around the axle (located at the door mechanism). This simple machine makes it easier to open and close doors by rotating the knob to move the latch or bolt.

1. Ramp: A ramp is a classic example of an inclined plane. It is gradually sloped and allows objects to be moved up or down with less force than it would require to lift them straight up. Ramps are commonly used for loading and unloading heavy items from trucks and for wheelchair access.
2. Slide: A slide at a playground is another example of an inclined plane. The sloped surface of the slide allows children to easily slide down from a higher to a lower level. The inclined plane reduces the effort needed to descend and provides a fun and enjoyable experience for children.

1. Screwdriver: A screwdriver is a tool that utilizes a screw to secure or fasten objects together. The screwdriver has a helical shaft with a pointed end that matches the screw's grooves, allowing it to turn and drive the screw into a material.
2. Jar lid: A jar lid often has a screw mechanism that allows it to be twisted securely onto the jar. By turning the lid clockwise, the helical threads on the lid interact with the threads on the jar, creating a secure seal that prevents leaks and keeps the contents fresh.
