What is the primary purpose of a simulation?

• Predicting future system behavior
• Building the real thing
• Influencing future behavior
• Testing hazardous scenarios

When might it be safer to use computer models instead of real situations?

• In chemical processes
• In everyday tasks
• In common scenarios
• In remote locations

What advantage does computer modeling offer when compared to real-life testing?

• Trying out various scenarios in advance
• High-risk situations
• Cost-effectiveness
• Trustworthiness of results

What can affect the quality of a computer simulation?

• Programming and data entered
• Trust in the results
• Cost of building the real thing
• Real-world scenarios

Why might people not always trust the results of a computer simulation?

• Discrepancies between modeling and reality
• Expensive modeling costs
• Real-world applications
• High-speed simulations

Why is 3D computer modeling used in the design of buildings and bridges?

• To test design scenarios before construction
• To save construction costs
• To create artistic designs
• To streamline the construction process

What is one advantage of using computer modeling for bridge and building design?

• Detecting potential design flaws early
• Reducing the need for scale models
• Enhancing artistic elements
• Reducing construction time

When designing a bridge, which scenarios might need to be considered when using computer modeling?

• Traffic jams, strong winds, earthquakes
• Floods, fire, elevator efficiency
• Human occupants' comfort
• Design aesthetics

In the context of building design, why is wind movement a key issue with tall buildings?

• Tall buildings may sway in strong winds
• Tall buildings are more earthquake-prone
• Tall buildings have complex designs
• Tall buildings have more elevators

What is one advantage of using a scale model and wind-tunnel tests after computer modeling?

• Validating the computer model results
• Reducing the cost of construction
• Enhancing the aesthetic appeal
• Avoiding the need for computer modeling
