My Simple machines Emma

This guide explains the six basic types of simple machines: levers, inclined planes, screws, wedges, wheels and axles, and pulleys. A lever transforms effort into motion using a fulcrum, while an inclined plane reduces the effort needed to elevate objects. Screws function by twisting a ridge, and wedges are used to split or separate materials. The wheel and axle create movement, and pulleys change the direction of force. Each machine exemplifies mechanical advantage, making work easier by efficiently applying force and motion.

  1. My Simple machines Emma By: Emma Hardy

  2. Lever Third class lever • A bar which turns on a fixed support called a fulcrum and is used to transmit effort and motion

  3. Inclined Plane • Plank or other plane surface set at an acute angel to a horizontal surface

  4. Screw • Kind of rail with a ridge twisted evenly around its length and often a groove across the head

  5. Wedge • 1 piece of wood or metal tapering to a thin edge, used in splitting, separating , ect. It

  6. Wheel and Axel • Axel on which a wheel is fastened, used to lift weights by winding a rope onto the axel as the wheel is turned

  7. Pulley • 1 wheel with a grooved rim in which a rope can run and so change the direction of a pull

  8. Gear • Wheel that rotates, the wheel has teeth

  9. Machine • 1 arrangement of fixed and moving parts for doing work, each part having some special function

  10. Work • Effort needed to move a certain distance

  11. Force • Energy needed to move a object

  12. Mechanical Advantage • The ratio of resistance or load to the force or effort that is applied in a machine
