What is a variable in engineering?

• A constant value

• A condition or value that can be changed

• A value that cannot be controlled

• A fixed value

What is the purpose of asking 'what-if' questions in engineering?

• To ignore variables

• To avoid solving problems

• To stick to the original plan

• To identify variables and potential changes

What is one variable that can be controlled when attempting to cross a gorge with a hang glider?

• Weight of the hang glider

• Gravity

• Height of the gorge

• Wind speed

What is an example of a variable that cannot be controlled when crossing a gorge with a hang glider?

• Design of the hang glider

• Weight of the hang glider

• Height of the gorge

• Wind speed

What is the purpose of building a prototype in the engineering process?

• To avoid making changes

• To finalize the design immediately

• To skip testing phase

• To test the solution before full implementation

What is the main step in the engineering process before building a prototype?

• Building the final product

• Choosing a solution that meets criteria

• Testing the prototype

• Defining variables

What is the role of engineers when a solution does not work during testing?

• Continue with the failed solution

• Go back to the drawing board

• Abandon the project

• Ignore the problem

Why is it important to identify variables when solving engineering problems?

• To understand what can be changed and controlled

• To complicate the problem-solving process

• To limit creativity

• To avoid finding solutions
