You, Alice, and Jodi are working together on a project to bring clean drinking water to a small village in an emerging country. The team has concluded their research of existing solutions and finished brainstorming ideas. To determine the best possible solution, the team used a rating scale shown in the table below. What is the name of the table?

Some members contribute more than others.
At the Oakridge National Laboratory (ORNL), researchers are tackling one of the UN global sustainability goals—responsible consumption and production—by finding new ways to recycle two troublesome waste products—waste tires and used cooking oil. The world creates about two billion scrap tires every year. Some waste tires are recycled into rubberized asphalt for highways and playground surfaces or landscape mulch. Waste tires can also be burned as fuel in place of coal or gas, but most tires are still sent to landfills or dumped illegally. Which of the following impacts should engineers consider when developing a solution?
Environmental impacts
Human health impacts
Safety impacts
Inequality impacts
All of the above
A comparison between the driven (out) gear and the driver (in) gear is called the:
power
acceleration
force – displacement
gear ratio
An idler gear can be used to:
change direction
increase spacing between gears
either A or B
neither A nor B
What is the primary goal of engineering?
To design buildings
To build machines
To apply science and math to solve problems
To write scientific laws
Which of the levers pictured is a first-class lever?
A
B
C
Given the pulley configuration shown in Figure 4, how many pound of effort force would a user have to exert on the rope to lift the 60-pound load?
15 pounds
20 pounds
25 pounds
30 pounds
Which of the following is a best practice for engineering notebooks?
Using pencil for sketches
Leaving pages blank
Skipping dates
Labeling all diagrams clearly
What is the first step in the engineering design process?
Build a prototype
Generate ideas
Define the problem
Communicate the results
Given a second-class lever with a distance of 5 feet from the fulcrum to the effort and a distance of 33 inches from the resistance to the fulcrum, what is the maximum amount of weight that can be lifted with 25lbs of effort?
165 lbs.
13.75 lbs.
45.45 lbs.

Read the narrative below. Choose the best answer that matches which step of the design process that is being described. The steps described do not necessarily happen in sequential order. Maddie and her team of engineers are working on redesigning their current engineering classroom at Hilliard Davidson HS. They will work together to solve the issues they find and develop a new classroom that will be innovative and allow students to maximize their experience in the pre-engineering program. Maddie and her team interview current and past engineering students to help them identify the criteria for a new room. From this they develop a design brief for their project.

Maddie and her team of engineers are working on redesigning their current engineering classroom at Hilliard Davidson HS. They will work together to solve the issues they find and develop a new classroom that will be innovative and allow students to maximize their experience in the pre-engineering program. The team fabricates and example desk for the new room and has students sit in the desk and give feedback on how it feels. These results are quantified to be analyzed later.

Maddie and her team of engineers are working on redesigning their current engineering classroom at Hilliard Davidson HS. They will work together to solve the issues they find and develop a new classroom that will be innovative and allow students to maximize their experience in the pre-engineering program. After considering ergonomics, size, cost and other factors, technical drawings are produced that would allow a build team to construct the room.
