What is the purpose of an idler gear?

What is the function of a hand crank?

It causes the driven to turn, and that moves the driving gear

It starts the motor

It helps to move the gears

How do the post standoff retainer or bearing flat parts provide stability to the shaft?

Post standoff retainers and bearing flat parts create a magnetic field around the shaft, repelling any forces that might cause it to move.

These components act like shock absorbers, absorbing and dissipating vibrations that could cause the shaft to destabilize. 

It keeps the pieces from wobbling

Why are collars inserted along the shaft, next to the gears?

They keep the gears in place.

They cause the gears to spin in the opposite direction the hand crank is being turned.

They help the gears spin in the correct direction.

What is an example of input?

the force applied to the gear as it spins

rotational speed of the gear

where the motion exits

where the motion starts

What is an example of output?

where the motion starts

where the motion exits

rotational speed of the gear

the force applied the to gear as it spins

What is the definition of input?

What is the definition of output?

What should you do if the brain icon in "VEXcode" is not green?

Connect the brain to the computer

It should automatically be green; this means the brain does not work

Restart your computer

It means the battery does not work, and should be replaced

Describe what the code to the left
does:

Two people working together to create a computer program. One person, called the driver, writes the code and explains the logic, while the other person, called the navigator, reviews it and gives feedback.

Paired Programming

Event

An ordered set of instructions that are used to carry out a task.

Flowchart

Paired Programming

Algorithm

Event

An action or occurrence that happens during runtime that will trigger a response or behavior by the software. Examples of events include user-initiated events, such as clicking a button, or external events, such as the device receiving an SMS text message.

For each of the following gear ratios (based on the number of teeth), determine whether the output speed increases, decreases, or stays the same.

12/12
12/36
60/48
24/72
48/48
36/12

Increase
Decrease
Stays the same

Why do designers and engineers care about gear ratios?

In the gear train, which way does the driven gear turn?

clockwise

counterclockwise

the driven gear does not move

there is no way to tell

What is the function of a hand crank?

It causes the driven to turn, and that moves the driving gear

It starts the motor

It helps to move the gears
