What is Energy
100
The application of force that moves an object a certain distance.
What is Work
200

If the larger gear is the input, is the mechanism built for speed or torque?  

Speed

200
Circular movement.
What is Rotary Motion
200
A push or pull on an object.
What is Force
200
A toothed wheel that works with others to alter the relation between the speed of an engine and the speed of the driven parts.
What is a Gear
300

If the input gear is the smaller gear, is the mechanism built for speed or torque? 

torque

300
A back and forth movement.
What is Reciprocating Motion.
300
A gear between the driver and the driven gear used to change rotational direction.
What is an Idler Gear
300
Toothlike projections arranged on a wheel rim to engage the links of a chain.
What are Sprockets
400
One transmits the energy into the system (input), and the other is the gear that the energy is transmitted to (output).
What is the drive and driven gears.
400

What movement in the output of the mechanism Cam and follower? 


Reciprocating

400
The ratio of the speed of the driving member of a gear train to that of the driven member.
What is a Gear Ratio
400

The part of a machine which contains two or more pieces arranged so that the motion of one compels the motion of the others.

What is a Mechanism

500

In the worm and wheel mechanism, the worm is used to ________ speed and _______ torque.  Because the wheel gear cannot drive the worm, the power is not reversible. 

decrease speed and increase torque

500
A swing back and forth at a regular rate.
What is Oscillate.
500
A connected flexible series of links used for fastening or securing objects and pulling or supporting loads.
What is a Chain
500
