Bridge Building
★Exhibit Content: Bridge Structures and Mechanical Load-Bearing ★Interaction: Manual Assembly Interaction ★Operation: Understand the requirements for three bridge-building tasks and observe different structural modules; select building components and collaborate with peers to assemble an arch bridge, a Bailey bridge, and a tension-balanced suspension frame; after assembly, observe the structural load-bearing characteristics and summarize the load-bearing advantages of each type of bridge. ★Exhibit Description: The exhibit includes three types of bridge assembly modules: arch bridge, Bailey bridge, and tension-balanced suspension frame, and is a recommended exhibit from the PopsciCat Exhibit Store. The exhibit comes with multiple sets of colorful assembly components that can be quickly disassembled and assembled without additional tools. Visitors can independently select components to build different bridge models. During the assembly process, they can compare different structural forms, intuitively experience the structural differences of various bridges, understand engineering design concepts, experience the practical application of structural mechanics in building bridges, and appreciate the ingenious wisdom of ancient and modern bridge engineering. ★Scientific Principle: The Bailey bridge relies on mutual compression between components to generate squeezing force, transferring loads to both ends and achieving stable support without connectors; the arch bridge converts upper loads into axial pressure of the arch ring, with the arch feet bearing the thrust, providing excellent spanning and load-bearing capacity; the tension-balanced suspension frame relies on the tension of flexible cables and the support force of the frame to cancel each other out, forming a static equilibrium state. The three models intuitively demonstrate mechanical knowledge such as thrust, pressure, and tension, allowing visitors to understand how different structures distribute loads and achieve stable load-bearing.
