    Study Notes

    Simple Machines

    Simple machines are the basic components of more complex machines and mechanisms. There are six types of simple machines:

    1. Inclined Plane

    • A flat surface tilted at an angle
    • Examples: ramps, stairs, ladders
    • Advantage: reduces effort required to lift or move objects

    2. Lever

    • A rigid bar or beam that pivots around a fixed point (fulcrum)
    • Examples: seesaws, crowbars, door handles
    • Advantage: changes direction or magnitude of force

    3. Wheel and Axle

    • A circular object that rotates around a fixed axis
    • Examples: bicycle wheels, gears, pulleys
    • Advantage: reduces friction and increases efficiency

    4. Pulley

    • A wheel with a grooved rim and a rope or cable wrapped around it
    • Examples: elevator systems, cranes, block and tackle
    • Advantage: changes direction of force or multiplies force

    5. Screw

    • A cylindrical object with a spiral ridge (thread)
    • Examples: screwdrivers, jar lids, spiral staircases
    • Advantage: converts rotary motion into linear motion

    6. Wedge

    • A triangular or tapered object that separates or holds objects apart
    • Examples: knives, axes, chisels, doorstops
    • Advantage: concentrates force or separates objects

    These simple machines are the building blocks of more complex machines and mechanisms, and are used in a wide range of applications in engineering, physics, and everyday life.
