Machines at play

Simple machines can be found

on school playgrounds

Is my thesis

I looked up all the information i needed

Simple machines can be found on playgrounds

Simple Machines and how they work:

Screw: Helps fasten two or more objects together.

Inclined Plane:Uses angled surfaces to move objects more easily.

Lever:A rigid bar on a central point used to help move a heavy or firmly fixed load with one end when pressure is applied to the other

Wedge:A piece of wood or some other material having one thick end and changing to a thin edge that is put between two objects or parts of objects to secure or separate them.

Wheel: A circular object that revolves on an axle and is fixed below a vehicle or other object to enable it to move easily over the ground.

Axle:a rod or spindle (either fixed or rotating) passing through the center of a wheel or group of wheels

Pulley: a small wheel with a grooved rim used with a rope or chain to change the direction of a pulling force and in combination to increase the force applied for lifting.

What is a simple machine?

A simple machine is any of the basic mechanical devices for applying a force.Simple machines can be regarded as the elementary "building blocks" of which all more complicated machines sometimes called “compound machines" are made. A simple machine is an object used to change the direction of motion or amount of required force A simple machine uses a single applied force to do work against a single load force.

Simple machines found on a playground:

Screw:N\A

Inclined Plane: Slide (Slides are inclined planes because they are ramps.)

Wedge: N\A

Lever: Seesaw,Swing

Wheel and Axle:Merry Go Round

Pulley:Zipline

A slide is an example of an inclined plane because an inclined plane also known as a ramp is plane surface that is neither vertical or horizontal. This describes the “seating surface” of a playground slide.

A seesaw on a playground is an example of a lever because mechanically, a seesaw is a lever which consists of a beam and fulcrum with the effort and load on either side.

A merry go round on a playground is an example of a wheel and axle because unlike a doorknob, this wheel and axle increases the distance the wheel travels, not the amount of force needed to turn the axle.

A zipline on a playground is an example of a pulley because at their most basic, ziplines are simply cables connected between two points that slope downward. Passengers are fitted with a body harness that clips into the cable via a pulley. These pulleys are designed to reduce friction, allowing the rider to accelerate down the line at grin-inducing speeds.

N\A

In conclusion, we learned simple machines can be found on playgrounds and they help make playgrounds fun for kids to play on.
