A diagram displays six types of simple machines with labeled illustrations: inclined plane, wedge, screw, lever, wheel and axle, and pulley, each shown with real-world examples like ramps, axes, screws, seesaws, door handles, and pulleys lifting objects. A diagram of an inclined plane shows a block resting on a sloped surface. The angle of inclination is labeled theta, with arrows representing the force parallel to the plane (F) and the weight acting downward (W). Illustration showing two types of levers: on the left, a bar used to lift a rock with the fulcrum under the bar; on the right, a nutcracker cracking a nut with force applied at the handles. shadoof wedge Diagram showing two types of wheel and axle arrangements: on the left, large and small interlocking gears labeled with force and radius; on the right, a system of pulleys and ropes demonstrating mechanical advantage. pulley Illustration of two block and tackle pulley systems, each using multiple pulleys and ropes to lift a weighted box, showing how force is applied to raise the load more easily. An illustration of Archimedes' screw shows a helical screw inside a slanted tube, lifting water from a lower pool to a higher level when the handle at the top is turned. Illustration showing seven types of screws and screw heads in a row, including a cap screw, machine screw with oval head, setscrew with hollow head, self-tapping screw, flat-head wood screw, machine screw with Phillips head, and lag screw, each labeled beneath.
