- wedge
- change direction of applied force, used to split objects
- pitch
- a distance of uniform measure determined at a point on 1 unit to the same corresponding point on the next unit
- simple machine
- lever, wheel and axle, pulley, inclined plane, wedge, screw
- coupling
- a system used to connect and transfer energy from one part to another- usually shafts that rotate
- thread
- a spiral groove cut into the outside of a shaft or the inside of a hole used to hold parts together
- force
- a push or pull exerted by one object on another
- linkage
- a mechanical system of related moving parts or connections
- wheel and axle
- larger diameter requires less force to turn than a smaller diameter axle. turns rotarty motion into linear motion, rotating lever
- belt
- a continuous band that transmits motion from one pulley to another
- gear
- a wheel with teeth that will allow the transfer of horizon power when coupled to another gear
- ratchet
- a mechanism that consists of a bar or wheel having inclined teeth to allow effective motion in one direction only
- pulley
- wheel like simple machine used to reduce input force, change the direction of force applied, or to increase the input distance
- gear trains
- a set of gears used to transmit power, change output direction, or change speed or force
- bearings
- devices used to reduce friction between rotating shafts and fixed carriers
- shafts
- cylindrical rods that support pulleys, gears, and sprockets to transmit torque
- friction
- a force that opposes the motion or intended motion of a body in contact with another body
- sprocket
- circular mechanical device with teeth that is used to import motion to chains
- inclined plane
- a flat sloping surface along which an object can be pushed or pulled, a plane surface that makes an oblique angle with the plane of the horizon
- cam
- a mechanical devise used to change simple rotarty motion into a more complex motion
- seal
- a device to prevent the passage or return of gas, liquid, or air into a pipe or container, a tight and perfect closure.
- crankshaft
- a shaft that has journals which changes reciprocating motion to rotary motion
- chain
- a continuous band consisting of metal or plastic links that transmits motion from one sprocket to another
- lever
- a rigid piece that transmits and modifies force or motion when forces are applied at 2 pints and it turns about a third
- screw
- a simple machine that uses threads to apply force, a spiral incline plane surrounding a center shaft
