Tilting, or leaning, refers to the act of bending or inclining at an angle rather than standing upright. This can occur in various contexts, such as when a person leans against a wall for support or when a structure, like a building, shifts due to uneven ground. In engineering, tilting is an important consideration for stability and safety. For example, the famous Leaning Tower of Pisa is a result of tilting caused by unstable foundation soil. Understanding the principles of tilting helps in designing structures that can withstand forces without collapsing.
