Term | Definition |
---|---|
actuator | a component of a machine that is responsible for moving and controlling a mechanics |
bearing | metal piece that is used to reduce friction |
cylinder | device that uses the pressure of fluid to move a piston that is connected to a rod |
fluid motor | a motor commonly of the turbine type that is driven by water or compressed air |
force | strength or energy as an attribute of physical action or movement |
gear | one of a set of toothed wheels that work together to alter the relation between the speed of a driving mechanism and the speed of the driven parts |
horsepower | the power of an engine measured in terms of this |
inclined plane | plane inclined at an angle to the horizontal |
lever | a rigid bar resting on a pivot, used to help move a heavy or firmly fixed load with one end when pressure is applied to the other |
mechanical advantage | the ratio of the force produced by a machine to the force applied to it, used in assessing the performance of a machine |
mechanical engineering | designing, building, and maintaining of mechanical, thermal, and fluid systems |
pneumatic systems | system that uses air transmit power |
power | rate at which work is done or energy is transmitted |
pulley | simple machine that consists of a wheel and rope used to move objects |
rotary actuator | device that can provide a small amount of rotation |
screw | simple machine that is an inclined plane wrapped around a cylinder |
simple machine | tool that makes work easier;includes the lever, inclined plane, wheel and axle, screw, wedge, and pulley |
valve | device used to control either the rate or direction of the fluid flow |
wheel and axle | simple machine that uses a circular wheel with an axle in the middle to create a mechanical advantage |
