Springs - Compression, TaperedAn extension spring, also known as a drawbar spring, is a type of mechanical spring that is designed to store energy and exert a pulling force. Extension springs are typically made from metal and have a cylindrical shape, with loops or hooks on each end. They are used in a wide range of applications, including automotive, aerospace, and industrial machinery.
Extension springs are typically used in applications where a force needs to be applied in order to extend or stretch the spring. They are often used in conjunction with other mechanical components, such as levers, gears, and pulleys, to transmit and amplify the force generated by the spring. Extension springs are available in a variety of sizes and materials, and they can be customized to meet the specific needs of a given application. Some common uses for extension springs include automotive suspension systems, latch mechanisms, and garage door openers.
