What are the three main parts of a system?

• Inputs, Processes, Outputs

• Sensors, Motors, Controllers

• Code, Prototypes, Iteration

• Safety Practices, Impacts, Collaboration

Answer explanation

The three main parts of a system are Inputs, Processes, and Outputs. Inputs are the resources or data that enter the system, Processes are the actions taken on those inputs, and Outputs are the results produced by the system.

What is the purpose of creating prototypes in engineering?

• To finalize the design

• To test ideas before building the final product

• To document the design process

• To improve safety practices

Answer explanation

The purpose of creating prototypes in engineering is to test ideas before building the final product. Prototypes allow engineers to explore design concepts, identify issues, and make improvements without the cost of full production.

Which of the following is a skill essential for working well in a team?

• Iteration

• Collaboration

• Prototyping

• Coding

Answer explanation

Collaboration is essential for working well in a team as it involves effectively communicating, sharing ideas, and supporting each other to achieve common goals. The other options, while useful, do not directly address teamwork.

What is the purpose of gears in a machine?

• To detect the environment

• To transfer motion and change speed or force

• To write instructions for a robot

• To create detailed sketches

Answer explanation

Gears in a machine are essential for transferring motion between components and can change the speed or force of that motion, making them crucial for efficient operation.

What does STEM stand for?

• Science, Technology, Engineering, and Mathematics

• Systems, Tools, Equipment, and Machines

• Safety, Testing, Evaluation, and Management

• Sensors, Technology, Engineering, and Mechanics

Answer explanation

STEM stands for Science, Technology, Engineering, and Mathematics. This acronym represents key fields of study that are essential for innovation and development in various industries.

Why is brainstorming important in the design process?

• To generate many creative ideas

• To finalize the design

• To test the final product

• To ensure safety practices

Answer explanation

Brainstorming is crucial in the design process as it allows teams to generate many creative ideas. This phase encourages free thinking and collaboration, leading to innovative solutions that can be refined later.

What is the role of sensors in a robot?

• To control the robot's movements

• To detect the environment

• To power the robot

• To provide feedback to the user

Answer explanation

Sensors in a robot primarily serve to detect the environment, allowing the robot to perceive and interact with its surroundings effectively. This capability is crucial for navigation and task execution.

How can engineers ensure their solutions are ethical and sustainable?

• By focusing on cost reduction

• By creating safe, ethical, and sustainable solutions

• By using the latest technology

• By minimizing the use of resources

Answer explanation

Engineers can ensure their solutions are ethical and sustainable by creating safe, ethical, and sustainable solutions. This approach prioritizes the well-being of society and the environment over mere cost reduction or technology use.

What is the purpose of taking notes and keeping drawings during the design process?

• To create a final product

• To document ideas and organize the process

• To test the design

• To ensure safety

Answer explanation

Taking notes and keeping drawings during the design process helps to document ideas and organize the process, ensuring clarity and continuity as the design evolves.

How can engineers adapt to challenges during a project?

• By ignoring the problem

• By adjusting when things don't go as planned

• By sticking to the original plan

• By avoiding risks

Answer explanation

Engineers can effectively adapt to challenges by adjusting their approach when things don't go as planned. This flexibility allows them to find solutions and keep the project on track, unlike ignoring problems or sticking rigidly to the original plan.
