Helical Spring - Open & Closed Coil

The Closed Coil Helical Spring is called Tension or Extension Spring and Open Coil Helical Spring is called Compression Spring. Helical Spring is made by winding of spring steel wire by red hot coiling or cold coiling.Difference Between Close Coiled and Open Coiled Helical Length of the spring and its capability to deflect under external loading greatly rely on this gap. When the coils are wound tightly in such a way that there exist no noticeable gap between two adjacent coils then the corresponding spring is termed as close coiled helical spring.A close coiled helical spring of round steel wire 10 mm , close coiled helical spring steelsJul 01, 2019 · A close coiled helical spring of round steel wire 10 mm diameter having 10 complete turns with a mean radius of 60 mm is subjected to an axial load of 200 N.
