Refer to the simple gear train setup in the photo. Select the correct statement:
There are two input gears and one output gear.
There are one input gear, one idler gear, and two output gears.
There are one input gear and two output gears.
There are two idler gears and one output gear.
How is a build guide a useful communication tool for engineers?
It tells the robot exactly what to do, saving you time.
It provides clear step-by-step instructions to help you assemble parts successfully.
It builds the product for you so that it is done correctly.
It provides several different build options so that everyone in the class has a different final system, some of which will not work.
What is one benefit of adding a loop to an algorithm (set of instructions)?
If you need to edit the code where the loop occurs, you will need to update the code in several places.
Adding a loop will require you to write the same set of code multiple times.
By adding a loop, the algorithm will always run only once and then automatically stop.
Using a loop will reduce the number of steps and time you spend writing and editing the code.
Davonte, Emma, and Aleks are working together to create an algorithm for their robot with the following design requirements: - The robot must move forward and backward. - The code must include a loop. - The code must include a wait or pause. - The code must continue to repeat for as long as the program is running. They came up with the code above, but it isn’t successful. How can the group debug their algorithm to meet the design requirements?
They need to replace the repeat loop with a wait loop.
It is coded correctly; they should check their hardware connections.
They need to replace the repeat loop with a forever loop.
They need to replace the repeat loop with a drive loop.
When looking at two different gear train setups, you record the following information in your data notebook.
In Setup 1, the driving gear is larger than the driven gear
In Setup 2, the output gear is larger than the input gear.
In Setup 1, the driven gear is larger than the driving gear.
In Setup 2, the driven gear is larger than the driving gear.
Which of the following statements is true?
When designing a solution to a problem, there is only one correct way to do it.
If a client is hiring you for a project, it is ok not to follow all the client’s design requirements.
You should always document your sketches and ideas in your PLTW Gateway Notebook.
You must fail before you can make any improvements to your design.
Why is it important to repeatedly test your design as you are building it?
To troubleshoot any problems that may occur.
To ensure that it meets the design requirements.
To try out different improvements to the design.
All of the above answers are correct.
After learning how to create algorithms, you realize you have a strong interest in learning more about creating programs in high school to determine whether the skill could be a possible career path for you. What types of classes would help you specifically learn more about coding?
When practicing pair programming, the driver’s job is to (a) the code, and the navigator’s job is to review the code.
Which of the following statements is true while creating a prototype? Select all that apply.
It should look exactly like the final product.
You should spend all your time decorating it.
It should meet all the design requirements.
It should function properly.
This system is referred to as a (a) .
A group of students is working together on a product solution, and they decide they should establish team norms. Why is this important to do before they begin?
It sets the expectations for how long each person will spend on each task.
It allows for each person to choose their own task, so they do not need to interact with one another.
Your group created the following program for your product prototype. Select the two statements that are true.
The door is programmed to stay open for 1 second.
If an object is detected, the door will open, and an LED will turn on.
The algorithm will run 90 times and then stop.
The door is programmed to stay open for 5 seconds.
Gianna and Maria created the following program. What is the conditional statement in this program?
(a)
