Models and Simulations in Engineering

The video explores the role of imagination in engineering, focusing on models and simulations. It describes three types of models: physical, mathematical, and process models, and three types of simulations: live, virtual, and constructive. The video highlights the applications and benefits of simulations in various fields, emphasizing their role in testing, cost reduction, and safety enhancement.

What is a physical model in engineering?

• A model that uses numbers to describe a product

• A model that looks and feels like the actual product

• A model that uses simulated people and situations

• A model that outlines steps to complete a task

Which type of simulation involves real people using real systems?

• Virtual simulation

• Mathematical simulation

• Constructive simulation

• Live simulation

How do virtual simulations differ from live simulations?

• They use real people and real systems

• They use simulated systems operated by real people

• They are only used in video games

• They use simulated people and situations

What is the primary benefit of using constructive simulations?

• They are costlier than other simulations

• They enable testing and improvements before production

• They allow for real-time testing with real people

• They help in visualizing the final product

Why are simulations important in engineering?

• They increase the cost of product design

• They ensure safety and reduce costs

• They are only used for training purposes

• They replace the need for physical models
