Tie rods are essential components in various mechanical systems, primarily used to provide structural support and maintain alignment. They are typically long, slender rods made of strong materials like steel, designed to withstand tension and compression forces. In vehicles, tie rods connect the steering mechanism to the wheels, ensuring precise handling and stability. In construction, tie rods help stabilize structures by holding different parts together, preventing movement or collapse. They are often used in bridges, buildings, and other large structures. Proper installation and maintenance of tie rods are crucial for safety and performance in both automotive and construction applications.
