Instructions

Using your notes, answer the questions to the best of your ability. 

Required

1

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

Required

2

What is the purpose of an idler gear?

Required

1

What is the function of a hand crank?

Required

1

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

Required

1

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

Required

1

What is an example of input?

Required

1

What is an example of output?

Required

2

What is the definition of input?

1

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

Required

2

Describe what the code to the left
does:

Required

1

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.

Required

1

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

Required

1

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.

Required

1

A block of code that is triggered when a certain event happens.

For the next four
 questions, assume that the output gear is on the right side of the gear train. 

Required

1

For this gear train, does the output speed increase, decrease, or stay the same?

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

Why do designers and engineers care about gear ratios?
