ABET |
The recongnized accreditor for college and university programs in applied science, computing, engineering, and technology |
|
Actual Mechanical Advantage |
The ratio of the magnitude of the resistance and effort forces applied to a system. |
|
Belt |
A continuous band of tough flexible material used to transmit motion and power within a pulley system. |
|
Career |
A profession for which one trains and which is undetaken as a permanent calling. |
|
Chain |
A series of usually metal links or rings connected to or fitted into one another and used to transmit motion and power within a sprocket system. |
|
Effort force |
An external force applied to an object. |
|
Efficiency |
The ratio of useful energy output to the total energy input, or the percentage of the work input that is converted to work output. |
|
Friction |
The resistance that one surface or object encounters when moving over another. |
|
Fulcrum |
The fixed point around which a lever rotates. |
|
Gear |
A circular toothed object used to transfer rotary motion and torque through interlocking teeth. |
|
Ideal Mechanical Advantage |
Ratio of distance traveled by the applied effort and resistance force within a system. |
|
Idler gear |
A gear positioned between the driver and the driven gear used to change rotational direction. |
|
Inclined plane |
A flat surface set at an angle or and incline with no moving parts that is able to lift objects by pushing or pulling the load. |
|
Lever |
A rigid bar used to exert a pressure or sustain a weight at one point of its length by the application of a force at a second and turning at a third on a fulcrum. |
|
Mechanism |
The structure of or the relationship of the parts in a machine, or in a construction or process comparable to a machine. |
|
Moment |
The turning effect of a force about a point equal to the magnitude of the force times the perpendicular distance from the point to the line of action from the force. |
|
Pitch |
Distance between adjacent threads in a screw. |
|
Pulley |
A type of lever that is a wheel with a groove in its rim, which is used to change the direction of multiply a force exerted by a rope or cable. |
|
Resistance force |
Impeding effect exerted by one material object on another. |
|
Screw |
An inclined plane wrapped around a cylinder, forming the path and pitch. |
|
Simple machine |
Any of various elementary mechanisms including the lever, the wheel and axle, the pulley, the inclined plane, the wedge, and the screw. |
|
Sprocket |
A toothed wheel whose teeth engage the links of a chain. |
|
Static equilibrium |
A condition where there are no jet external forces acting upon a particle or rigid body and the body remains at rest or continues at a constant velocity. |
|
Technical communication |
Creating, designing, and transmitting technical information so that people can understand it easily and use it safely, effectively, and efficiently. |
|
Torque |
A force that produces or tends to produce rotation or torsion. |
|
Wedge |
A substance that tapers to a thin edge and is used for splitting, raising heavy bodies, or for tightening by being driven into something. |
|
Wheel and axle |
Two different sized circular objects that are attached together and then as one. |
