| \( D \) = mean coil diameter | \( in \) | \( mm \) |
| \( D_i \) = inner diameter | \( in \) | \( mm \) |
| \( D_o \) = outer diameter | \( in \) | \( mm \) |
| \( d \) = wire diameter | \( in \) | \( mm \) |
Spring mean coil diameter is the average diameter of the helical coil in a spring. It is used in designing and analyzing the performance of springs, as it influences the spring's stiffness, load-bearing capacity, and stress distribution.
