Physical structures refer to tangible constructions that provide support and shelter. These can include buildings, bridges, and towers, which are designed to withstand various forces such as gravity and weather conditions. The materials used, such as steel, concrete, and wood, play a crucial role in determining the strength and durability of these structures. In addition to their functional purposes, physical structures often have aesthetic value. Architectural design considers both form and function, leading to iconic landmarks like the Eiffel Tower or the Sydney Opera House. These structures not only serve practical needs but also contribute to the cultural and historical identity of a place.
