Simple Machines
Simple Machines Understanding Simple Machines: The Building Blocks of Mechanics Simple machines are the fundamental tools that make work easier by reducing effort or changing the direction of force. They form the basis of many complex machines we use today. There are six types of simple machines: 1. The Lever A rigid bar that pivots around a fixed point (fulcrum) to lift or move loads. Examples: seesaws, crowbars, and bottle openers. 2. The Pulley A wheel with a rope or chain that helps lift heavy objects by changing the direction of force. Examples: flagpoles, cranes, and elevators. 3. The Wheel and Axle A circular frame (wheel) attached to a central rod (axle) that helps in transportation and mechanical advantage. Examples: cars, bicycles, and door knobs. 4. The Inclined Plane A flat surface set at an angle that reduces the effort needed to raise objects. Examples: ramps, slides, and staircases. 5. The Wedge A piece of material with a sharp edge used to split or hold objects in...
