A Case of 'What-Ifs'

The video explores the concept of what-if questions and their significance in engineering. It recaps the engineering process, emphasizing the importance of defining and understanding variables. The video explains how variables can be controlled or uncontrollable and uses practical examples to illustrate these concepts. By identifying variables and asking what-if questions, engineers can better test and refine their solutions to problems.

Why are 'what-if' questions crucial for engineers?

• They help in predicting the future.

• They assist in finding solutions to problems.

• They are used to entertain engineers.

• They are only used in theoretical scenarios.

What is the first step in the engineering process?

• Defining a solvable problem

• Identifying variables

• Building a hang glider

• Testing prototypes

Which of the following is an example of a variable that engineers can control?

• Gravity

• Wind speed

• Rainfall

• Weight of a hang glider

What role do 'what-if' questions play in the engineering process?

• They are irrelevant to the process.

• They are only used for documentation.

• They are used to finalize the solution.

• They help in identifying potential changes in variables.

Which of the following is a variable that cannot be controlled by engineers?

• The angle of the wings

• The design of a hang glider

• The weight of the passengers

• The wind over a gorge
