Front 5

Chain

Back 5

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.

Front 6

Effort force

Back 6

An external force applied to an object.

Front 7

Efficiency

Back 7

The ratio of useful energy output to the total energy input, or the percentage of the work input that is converted to work output.

Front 8

Friction

Back 8

The resistance that one surface or object encounters when moving over another.

Front 9

Fulcrum

Back 9

The fixed point around which a lever rotates.

Front 10

Gear

Back 10

A circular toothed object used to transfer rotary motion and torque through interlocking teeth.

Front 11

Ideal Mechanical Advantage

Back 11

Ratio of distance traveled by the applied effort and resistance force within a system.

Front 12

Idler gear

Back 12

A gear positioned between the driver and the driven gear used to change rotational direction.

Front 13

Inclined plane

Back 13

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.

Front 14

Lever

Back 14

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.

Front 15

Mechanism

Back 15

The structure of or the relationship of the parts in a machine, or in a construction or process comparable to a machine.

Front 16

Moment

Back 16

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.

Front 17

Pitch

Back 17

Distance between adjacent threads in a screw.

Front 18

Pulley

Back 18

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.

Front 19

Resistance force

Back 19

Impeding effect exerted by one material object on another.

Front 20

Screw

Back 20

An inclined plane wrapped around a cylinder, forming the path and pitch.

Front 21

Simple machine

Back 21

Any of various elementary mechanisms including the lever, the wheel and axle, the pulley, the inclined plane, the wedge, and the screw.

Front 22

Sprocket

Back 22

A toothed wheel whose teeth engage the links of a chain.

Front 23

Static equilibrium

Back 23

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.

Front 24

Technical communication

Back 24

Creating, designing, and transmitting technical information so that people can understand it easily and use it safely, effectively, and efficiently.

Front 25

Torque

Back 25

A force that produces or tends to produce rotation or torsion.

Front 26

Wedge

Back 26

A substance that tapers to a thin edge and is used for splitting, raising heavy bodies, or for tightening by being driven into something.

Front 27

Wheel and axle

Back 27

Two different sized circular objects that are attached together and then as one.
