Solid Structures
Solid structures have a stable and rigid framework of atoms, ions, or molecules. Density measures how compact the atoms or molecules are. Hardness resists deformation. Melting point changes a solid to a liquid. Solid structures rely on solid components and have great mass.
Structural Use of Solids
Solid structures use solid materials to support loads. Density measures compactness of atoms or molecules. Hardness resists deformation. Melting point changes a solid to a liquid. Bridges, buildings, houses, and backpacks are examples of solid structures.
Characteristics of Structural Solids
Solids have rigidity, resistance to force, and shape retention. Properties include conductivity and density. Ionic solids have lattice energy and crystalline structure. Foundations support houses by withstanding loads.
Structures Formation and Classification
Structures form by differential settling. Structures classify by solid, frame, or shell forms resisting different loads. Characteristics of solids include rigidity and resistance to force. Chairs, walls, and roofs are examples of solid structures. Buildings use mass, frame, or shell designs to resist natural disasters and heavy winds.
