💪 Strengthening Structures
Learn how to identify and apply factors that make structures stronger and more stable. This quiz focuses on practical methods engineers and builders use to improve structural designs through supports, bracing, material selection, triangulation, and proper fastening techniques. **What you'll learn:** - How adding supports and bracing increases structural strength - Why triangular shapes and proper fastening are important in construction - How to apply these principles to modify and improve designs - The role of material choice in building stronger structures
