Spring News June Issue" includes a trivia about springs: "What is the effective number of coils?
The June issue of the Spring News delivered every month! It is considered good to have a valid number of volumes of 3 or more.
The effective number of coils refers to the portion of the coil that acts as a spring, calculated by subtracting the number of end coils from the total number of coils in a compression spring. Generally, end coils are often one coil each at both ends, so in that case, the effective number of coils is total coils minus 2. If the first coil and the last coil do not contact the next (previous) coil, and the ground portion is 3/4 of a coil, the effective number of coils becomes total coils minus 1.5. It is considered good practice to have an effective number of coils of 3 or more. For tension springs, the total number of coils equals the effective number of coils (excluding the hook sections).
