Simple Machines

Simple machines are fundamental devices that make work easier by allowing us to manipulate force and motion. Inclined planes, such as ramps and ladders, facilitate the movement of objects between different heights. Wedges, like axes and knives, help cut or split materials. Screws combine inclined planes wrapped around a cylinder to bind or lift objects. The wheel and axle simplify movement over distances, while pulleys enable lifting with minimal effort. Levers, classified into three types, pivot around a fulcrum to lift and move loads efficiently. Explore how these machines enhance our daily tasks.

  1. Simple Machines

  2. Inclined Plane Definition: A slanting surface connecting a lower level to a higher level How it makes work easier: It is used to help things move up or down distances Examples: Ramps, stairs, slide, escalator, slope

  3. Wedge Definition: An object with at least one slanting side ending in a sharp edge, 2 inclined planes put together How it helps make work easier: Cuts or spreads an object apart or fastens objects Examples: Doorstop, axe, thumbtack, knife, snowplow, chisel

  4. Screw Definition: An inclined plane wrapped around a pole/cylinder How it makes work easier: Holds things together or lifts things Examples: Screw, propeller, fan, jar lid, drill

  5. Wheel and Axle Definition: A wheel with a rod through its center, both parts move together How it makes work easier: Lifts or moves loads across distances Examples: Wagon wheel, doorknob, car, bike

  6. Pulley Definition: Cable or rope wrapped around a grooved wheel. As the wheel rotates, the cord moves How it makes work easier: Helps lift things up and down or move them across Examples: Flagpole, clothesline, tow truck, crane

  7. Lever Definition – A stiff bar that rests on a support called a fulcrum. It pivots (turns) against the fulcrum. There are 3 types, and the types is determined by where the fulcrum is. The types are 1st class, 2nd class, and 3rd class. How it makes work easier: It lifts and moves loads.

  8. 1st class Examples: seesaw, scissors, crowbar

  9. 2nd class lever Examples: wheelbarrow, nutcracker

  10. 3rd class lever Examples: broom, shovel, bat
