What are some types of loads that act on a bridge?

• Traffic such as trains, trucks, bikes, people and cars
• Winds, hurricanes, tornadoes, snow, earthquakes, rushing river water, and sometimes standing water
• Both A and B
• None of the above

What is the next step after determining the types of loads or forces the bridge will carry?

• Brainstorming design ideas
• Understanding the problem completely
• Calculating the amount of material required to resist the loads
• Determining if these loads can occur at the same time

What is the purpose of calculating the largest anticipated force from all the possible load combinations?

• To determine the types of loads or forces the bridge will carry
• To brainstorm different design ideas
• To calculate the amount of material required to resist the loads in that design
• To determine the highest possible force (stress) on the bridge

What is the final step in designing a bridge?

• Brainstorming design ideas
• Understanding the problem completely
• Calculating the amount of material required to resist the loads
• Splitting the design into smaller parts

What is the purpose of splitting the design into smaller parts?

• To make the design more complicated
• To make the design easier to understand
• To make the design more expensive
• To make the design more difficult to build
