Which component first generates the turning motion?
The Wires
The Motor
The Fan Blades
The Axle
Which components are part of the "transmission"?

The Motor
The Fan Blades
The Axle
The role of the VEX Brain is to provide power to the motors.
True
False
Mechanical advantage for gears involves a tradeoff between:
Weight and Torque
Speed and Distance
Weight and Speed
Torque and Speed
If you wanted a fan that would spin as fast as possible, which of the following gear configurations is theoretically best?
All large gears to cover more distance
Different gear combinations, including really large and small gears
All small gears to spin faster
No gears: It should be direct driven
A system with a mechanical advantage of 1:5 is:
5 times faster, but 1/5 as forceful
5 times slower, but 1/5 as forceful
1/5 as faster, but 5 times more forceful
How many turns does the small gear (16 teeth) need to make in order to keep up with one turn the large gear (60 teeth)?
1 Turn
1.5 Turn
5 Turns
2 Turns
Compared to a same-size gear train, how many times faster will the fan spin with a 36-tooth gear on the motor driving a 12-tooth gear on the hub?
0 times faster. The speed of the fan doesn't change.
3 times faster. The gear on the motor is 3 times larger than the gear on the hub.
6 times faster. The gear on the motor is 6 times larger than the gear on the hub.
The fan will actually spin 3 times slower because of the gear difference.
The gears in this arrangement form a:
Sequential Variables
Gear Pack
Gear Train
Transmittal Interconnections
The "transmission" system in the fan includes:
Axles, Basedrums
Gears, Axles
Hubs, Brain
Brain, Gears

The Brain
The Motor
What component is this?
The Controller
The Radio
The Brain
The Motor
When a gear turns another gear that is the same size, they turn the___________, and in the ___________.
same amount, opposite direction
same amount, same direction
different amount, opposite direction
different amount, same direction
In this example, idler gears are used to change the direction the driven gear spins. How many idler gears are there?
1
2
3
4
The gear attached to the fan is the _________ since it is connected to the output (the thing we want to move) of the system.
Wheel
Idler Gear
Driven Gear
Gear System
