How does a decrease in temperature affect arch materials?
Think about what happens to materials in colder weather.
What is rib shortening?
Focus on the relationship between temperature and rib length.
What happens to structures when the temperature drops?
Consider basic physics of temperature and materials.
True or False: Rib shortening can compromise an arch's load-bearing capacity.
Think about how arches bear loads.
Design a hypothetical arch that can handle a temperature drop of 100°F. Describe how you would account for rib shortening in your design.
Consider both materials and design features.
Given a scenario where an arch's rib shortens unexpectedly, propose a series of structural adjustments that could mitigate failure.
Think about practical alterations to existing structures.
