Define Coil in Springs?

A coil in springs refers to the individual loop or turn of the wire that forms the helical shape of the spring. The number of coils, their diameter, and spacing determine the spring's mechanical properties, such as stiffness and load-bearing capacity. Coils allow the spring to compress, extend, or twist, enabling it to absorb and release energy. The design of the coils influences the spring's performance, with tightly wound coils providing higher stiffness and widely spaced coils offering greater flexibility. Coils are essential in various types of springs, including compression, extension, and torsion springs.
