Structures are the buildings and frameworks that make up our environment. They can be as simple as a treehouse in your backyard or as complex as a skyscraper in a bustling city. Structures are designed to support weight and withstand various forces, ensuring they are safe and functional for people to use. In addition to buildings, structures also include bridges, tunnels, and even dams. Each of these plays a crucial role in connecting communities and providing essential services. Understanding structures helps us appreciate the engineering and creativity involved in creating the spaces we live, work, and play in every day.
