|
|
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.

|
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.

|
|
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 an 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 or 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 net 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 force that produces or tends to produce rotation or torsion.
|
|
|
Wheel and Axle
|
Two different sized circular objects that are attached together and turn as one.
